I’ve been reading Questionable Content for a while now, but recently I noticed a great bunch of references to MP3 blogs in a few strips. If you haven’t heard about this webcomic, here is a WikiPedia entry about Questionable Content.
Here are the strips:
One (#449), Two (#465), Three (#466), and Four (#468)
Jeph Jacques even created a Blogger account for the blog mentioned in the strips: Yelling About Music!
