Amy Winehouse's songs all seem to advance a story or heighten an emotion very well.
I've been working out how one would work in my head.
Though I do think that she needs at least one more good album before you can seriously consider her, as 2 albums and a bunch of B-sides does not a good jukebox musical make.
That made sense in my head before I typed it. LOL!
Unfortunately, even with her "rejuvenation" in the Bahamas somewhere, I think that she is too tragically a mess to complete a good third album.
Xanadu! Can't cry on cue!
