What do you use for listening to mp3s?

[ptech]

When I got the Imagio, I was excited about using this as an mp3 player since it had that microSD slot and a 3.55mm jack. But the included applications for music, the Music tab in touchflo and the Windws Media Player weren't very good interfaces. I'm looking for an intuitive, and simply functional player that works well with a touchscreen, and has album art and playlist functionality. I tried S2P, but are there any other out there? I'm a Zune user, so an interface like that would be awesome!
