Any alternative Music players for Songbird.

I use Songbird music player extensively, those who are not aware of this player here *www.getsongbird.com/

I like all the functionality provided by this player, but its a big memory hogger, At times it takes 200mb Paged memory. any better solutions available which provide same functionality.(iTunes is not my choice, anything else, FOSS will do.)

I am looking for Features:
1. lyrics display,
2. Last.fm audio scrobble support
3. should be able to play all mp3/aac/mp4 audio files.
4. smaller memory footprint.

Thanks in Advance.
