I do like the soundtracks, Noteflight's quality aside. Do you really have to create an account to get anything from 4share, though? Ah well.

Personally, I'd like to imagine that in Order of the Stick, background music would be diegetic, and the more genre-savvy characters would react to it. I suppose that the IFCC had the right idea in I See a Red Robe and I Want to Paint it Black.

Like, when Tarquin throws a fancy banquet, Eine Kleine Nachtmusik plays in the background. A genre-blind straight man asks where the band is, and Tarquin explains that there is no band, the music just spontaneously starts playing in the background whenever there's a hoity-toity formal banquet.

Or, just as Xykon and Redcloak are about to conduct the ritual and take control of the gate, Carmina Burana starts playing in the background, and Redcloak can make a disgusted remark about how trite it is and wish that he had anticipated it and prepared a silence spell in his daily prayers to the Dark One.

And so on...
