Partial answer
The first hint:
The Gratifying Enigmatic Brainteaser referenced in the first hint points to Douglas Hofstadter's book Gödel, Escher, Bach, which is sometimes called GEB.
The second hint:
The linked music is from Bach's The Musical Offering, a collection of keyboard pieces. This may just be a hint to help one see the connection to GEB. After all, GEB opens with a discussion of a piece from the same collection.
There is a hint in the title:
The strange loop referenced in the title is an allusion to Hofstadter's concept of the same name, which is discussed in GEB.

input: 10-28 loop victim
st = new String(out); st = StringBuffer(st).insert(1,"M").toString();
Java code to insert 'M' into a string after the first letter. (This may be a reference to the toy formal language MIU presented in GEB, but I doubt it since the Java code is inconsistent with the syntactic rules of the language.)
