I am sure that you get sick and tired of people asking for recommendations of what to buy, but here comes another one. I'll give you my brief 1. Has to work with WMA files 2. Has to do playlists 3. Needs to play house mixes without putting gaps between songs (if this is posssible) 4. About 20 gig memory 5. Not bothered about it having ability to show pictures. 6. Longish battery life. I have looked at the Sony HD5 but been a bit nervous because of Sonic Stage. Also considered the Gigabeat and irivers.
