Baby Bash

The chorus for "Na Na" ("She's so yummy") doesn't exactly come off as dignified. But Baby Bash's nonchalant flow neutralizes any potential cheese; this guy can sing about his girl's "platinum nana" and still sound like you'd want him on your side in a bar fight. The skittering, guitar-laced production continually slips out from under your fingers, adding something sly and mysterious to what should be a straightforward love song.
