Raffi
I must be a child at heart. I still absolutely love songs from my childhood, as well as the books I grew up on. I need Raffi in my music collection, and I haven't gotten any yet. Last.fm has a whole bunch of his stuff up, but none of it available for free download *pout*. At least I know where to find it now, since youtube was sparse on his stuff.
Also, speaking of Raffi, I still want to put together a Pintsize costume for a convention some time, and wire it up with an mp3 player and speakers, and go around playing Raffi all day, like the guest comic where Pintsize was punished by being loaded up wiht nothing but Raffi tracks. That would be fun.
