OP's solution to the riddle "Wherever I may roam 2000"
individual lines get posted one by one, as they get solved
The overall answer (provided by Walt) is
(01) I never give a single hair to the carder (by Walt)
This is just a general hint that we are dealing with a bird here. Birds have feathers, so no hair for the carder.
(02) shrunken by boob, I try even harder (by M Oehm)
The crow tit is small bird (so the tit shrinks the crow here). Supposedly, the term "crow tit" is somewhat synonymous for "try hard" due to a Korean saying.
(03) drupy and pitted and jammed in the larder (by Walt)
Crow berries (which are drupes) can be cooked into jam. Jam typically requires pitting (removing the stones). And a larder is a typical storage place for the jars.
(04) but when throwing or dancing I'm jumping with ardor (not found)
The crow hop is a step technique used for instance in Baseball for stronger/farther throws, and also occurs as a move in fancy or freestyle dance.
(05) some call me small, but they don't know jack (by hagfy)
The jackbaw is the smallest type of corvus, the name literally meaning "small bird". If you know this Jack, than a common crow is not the small one.
Also it's a common misconception that crows are the smaller brethren of ravens, while actually both names are widely applied to a range of species (albeit mostly the "crow" being the smaller one than the "raven" of the region, AFAIK). If you know about the jackbaw, you probably know proper classification terminology and understand that calling crows small is simplified enough to being wrong.
(06) while one of my brothers plays chess, white and black (by M Oehm)
The Rook is a small type of corvus, and also a playing piece in chess. "White and black" was meant to hint at the playing pieces themselves.
(07) some say that I gleam from a chicken shack (not found)
(Yeah, I know I need to apologise, the meter here only works with the help of a sledgehammer)
Cockcrow is prosaic for "(at the) first light of day" (hence gleam and "cock" -> chicken shack). The word allegedly comes from the every-too-early-morning screaming fit of terror, alledgedly precisely 5 minutes before even the sun itself knows it's rising, that so spit-beggingly inheres in roosters.
(08) and some think that I fear some straw on a rack (by Walt)
A scarecrow is made of straw. And while it might work on some birds, it's notoriously useless in scaring away the very crows it's named after.
(09) at 14 I'll shine in regal resplendence (by M Oehm)
Crown. 14 here refers to the 14th letter of the alphabet "n". "At 14" here means "crow" at "n" = crown. A common item of royal pomp.
(10) as Sam I enjoy ornithovorous attendance (not found)
This one is totally straight, I'm surprised noone found it - naa, just kidding: Sam Crow is a pseudo name for the Acronym SAMCRO, which stands for "Sons of Anarchy Motorcycle Club Redwood Original" of the TV series "Sons of Anarchy". Several women hang out with the club as groupies, for members of Sam Crow to enjoy what they politely call attendance, and they are called crow eaters.
So more precisely that term should have been corvovorous, but I didn't want to give it away too easily ;-)
(11) add 4 and I'm many in interdependence (by M Oehm)
Crowd. The 4 to add is the 4th letter of the alphabet "d". Interdependence is what makes many a group.
(12) but careful, because I bring death, in abundance (by Walt)
a flock of crows is called a murder (hence the comma. It's to mean I in abundance, not bring death in abundance)
(13) you can call me Suzanne, do you like what I play? (by Walt)
Refers to the musician Sheryl Suzanne Crow
(14) for the king of games think of Hulk I portray (by hagfy)
Crow Hogan (reminiscent in name of Hulk Hogan) is a figure in Yu-Gi-Oh, which literally means King of Games. (He does not appear in the original series, but in spin-offs, but they are still named Yu-Gi-Oh something.) - I only found out after posting that there is a The Hulk card in the Yu-Gi-Oh CCG. I reworded the line to be less misleading. Sorry, tried to double-check everything before posting.
(15) I help you walk with your nerves gone astray (by Walt)
A Charcot Restraint Orthotic Walker, CROW for short, is an ankle/foot orthotic in form of a stable boot that helps with walking if the foot is sick with Charcot neuroarthropathy.
(16) but you get on your hands and mock how I stay (not found)
To assume the yoga crow pose you stand on your hands in a crouching (or maybe crowching) position and look silly. (I'm no expert, the last part might be non-obligatory, but even in people far more elegant than I am, it looks like mockery at best).
(17) I'm undead in caps, but get played by a dead (by Walt)
Refers to the movie The Crow (in caps meaning in capitals, hinting at it to be a title). The Crow character is an undead, a revenant, returned from the dead for vengeance.
Crow actor Brandon Lee tragically died during the filming of the movie. But with special effects, some scenes and thus the movie were completed even after his death.
(18) I stream ruby ponies with a rather short head (not found)
The Shorthead Redhorse is the most common fish in the crow river.
(Yeah I admit, I was short for one line. This one is just a very tiny bit forced.)
(19) bordering Spain I'm a trustworthy lad (by M Oehm)
Escrow. (Crow borderig ES, which stands for for Spain/Espana)
(20) but serve me a drink and I burgle instead (by M Oehm)
Crowbar. A drink is served at a bar. A crowbar is not uncommonly implemented in the context of burglary.
The title "Wherever I may roam 2000" refers to (possibly superseded by Walt :-)
The Britsh Countryside and Rights of Way Act 2000, or CRoW Act for short, which implements the "right to roam" to a broader area in November 2000.
Walt had a very different answer, and a very cool one, so i should make it official:
Metallica performed this song in Baltimore in 2000, and Baltimore's football team is called the Ravens, named after the poem by Edgar Allan Poe (who's buried in Baltimore).
And the bonus line: (basically solved by Walt)
The first album released by the Minneapolis-based band Crow, still named South 40 then, was called Live at Someplace Else.
When they recorded their first studio album "Crow Music", they already had changed their name to "Crow" and were contracted to Amaret Records.
The term bonus line was meant to ring like bonus track and hint on music albums.
