#4: FIONA APPLE

What to look forward to this year: Fiona Apple was the quintessential singer-songwriter of the '90s. Both her debut and sophomore albums, Tidal (1998) and When The Pawn. . . (1999) went multi-platinum and produced such hits as "Criminal," "Paper Bag" and "Fast As You Can." But in the 2000s, her impact was overshadowed by the softer, bubblier sounds of Michelle Branch and Sara Bareillis. It's safe to say, the new century deserves to recognize the pioneer of female modern-rock, and Fiona Apple is getting ready to do just that with her first album since 2005, set for release this spring.
