I love university radio stations! The clear channel stations suck -- it's all repeats of a couple of popular songs. But the local university station almost always has something I haven't heard before.
The other day they played Daydreamin' by Lupe Fiasco. And it turns out to be one of those songs with a fascinating past.
The Encyclopedia of Record tells us it was first recorded in 1968 as Daydream by The Wallace Collection.
I, Monster has a nice take on it.
The Pharcyde's She Said (with Fuzz Face from Portishead, naturally) rocks.
The Beta Band called theirs Squares.
Maybe later I'll look up some of the other songs in the wikipedia article.
