Playlist names won't sync

[BattleMetalChris]

I've been an iTunes user for about 4 years, but my faithful old 1G iPod Touch is finally dying, so I figured I'd combine my phone and media player and get a Samsung Galaxy S2.

Which of course meant no more iTunes.

I've got Winamp to import my iTunes playlists (and it's kept all the ratings too - very impressed), but when I go to sync the playlist to my phone, although the files sync fine, it's not actually syncing the playlist. The playlist appears neither in the default music app nor the Winamp for Android app. I can listen to the synced music if I select it by song/artist/whatever, but no playlists.

And ideas?
