You don't say if you're looking for strict rythem or not, and then there's the question of personal taste - I won't make any recommendations. But - here's a website I have found helpful in the past for finding songs. Strict and non-strict songs are provided, typically along with info on the album the song is found on. One caution: the page apparently includes "contributions" from several individuals, not of all of whom are *always* accurate between a waltz and a four-beat song. So - the site is helpful - but certainly not holy writ.
