I do remember she lost her mind over Tohoshinki at a-nation, haha
"Imagine" is pretty much one of EVERYONE'S favorite songs if they're really into music.
I remember the DOME TOUR 2001 History Book had one photo with a stack of mini-LP style CDs... The Rolling Stones' "Sticky Fingers" and RHCP's "BloodSugarSexMagik" among them. Dunno if they were hers, her band members', or what, but that photo WAS given a whole page, so that's probably just what everyone was listening to during DT2001 rehearsals.
In a Popteen interview she once mentioned liking P!NK's then-current album, and in I think the TIME Magazine interview she talked about buying Joan Osborne's "Relish" album because she liked "One of Us" when she heard it in the Vanilla Sky trailer.
