Which jukebox program do you use for Music?
Personally I use two
- Apple iTunes
- Sony Media Go
iTunes has the best visualizer ever since Apple bought Magneatosphere and it has the best organization structure (folders of playlists!!) in a pretty nice interface. Yeah it doesn't match the Aero UI and I think it would look pretty awesome if it did, but it is still nice looking.
Media Go has this fantastic feature called SensMe which basically analyzes all my music and can auto-generate playlists based on mood. Additionally it stays in sync with iTunes so I never have to futz around with organization since it just looks at what I've done in iTunes and auto updates the changes.
They both have great app stores built into them; iTunes lets me find iPad apps and Media Go gives PSP games.
