Heck yeah! I love seeing music references in comics! One of my favorites is how Blacksad references music for ambiance through out the books! He especially seems to have a thing for oldies music, though I guess that makes sense considering the timeline.
We have used a selection of music purposfully in our comic. One of our characters, Audrey, is a huge music nut, and we FINALLY got the chance to have her listening to music in the comic.
Specifically the chorus from Oblivion, by Mastodon.
I'm actually kinda curious. Say you're publishing a book that mentions lyrics like what I have above. How do you credit the music properly in a comic or written work? Like, I've read in a TON of novels music lyrics sang by the characters, or what have you. But how do you make sure you don't get sued into oblivion and properly credit the folks? :o
