One of my favourite ongoing mixtape plans is "songs that mention other bands or artists". I have a list of about 45 songs that do this, but I want other people's ideas first (plus, I don't want to be late to work)
So, it turns out if you don't link journal entries to artists (and you post it at a time that is inconvenient for the US and the UK) then you don't get many people reading it except people you actually know. Who you could have emailed for mix tape advice (and have done, several times in the past).
So, here are Misstriggercut's and Xenex's selections, and my own list:
Weezer -In the Garage (mentions Kiss)
Custard - If Yr Famous and You Know It Sack Yr Band (I can't think of who that song mentions, and I can't find the CD at the moment. So I don't know if it is the song you're thinking of)
