Your name is:
Alex Trebek, the host of the TV gameshow Jeopardy! (Note that 'Beret K' is an anagram of 'Trebek'...) You are 'normally the one with all the answers', since on Jeopardy! the challenge is for the contestants to identify the original question when provided with the answer by the host.
The paragraph can be interpreted as representing:
A series of musical notes, if you take the starting letter of each word (I had sussed this around the same time as @Deusovi's comment and before the hint, although it has taken me some time to parse the notes into a recognisable tune). It perhaps makes the most sense to space them as follows:
CGEF GCG GCGCE DCBAA GCG EFGCG CAGFEDC
Then if you listen to this, you will recognise it as...
the theme tune to Jeopardy! No wonder it's stuck in your head - you must have had it 'sung to you' thousands of times while recording the show!
PS It is worth noting a few other Easter eggs hidden by the OP (prompted by comments below):
- The name of the Jeopardy! theme tune is 'Think!'. The OP used the word 'think' within the puzzle itself, at the end of the very first line.
- The creator and producer of Jeopardy! was Merv Griffin - the use of 'Griffin' throughout the puzzle paragraph was a referential nod towards him.
- Griffin also composed the theme tune in question, and originally as a lullaby for his son, Tony. Since then it has gone through several re-workings over the years, although the original melody remains largely unchanged.
