I like the seemingly recent trend of artists paying tribute to other artists by mentioning them in their songs. Satisfies the music nerd in me that bands I like like other bands I like.
Post here songs that mention other artists.
I will start:
Daft Punk - Teachers
LCD Soundsystem - Daft Punk is Playing at my House
CSS - Let's Make Love (and Listen to Death From Above)
Vampire Weekend - Cape Cod Kwassa Kwassa
