I've used Spotify since fall of 2008. It's hands down the most amazing music service out there. Everyone that have I've showed it to pretty much fell in love with it.

Until today Spotify's mobile apps have only been available to premium subs. With this you can throw out iTunes and sync with your iPhone, Android etc. Sync over Wi-fi and playlist management is way simpler than iTunes.

Do they have a web version, though? I'd much rather not have to download a client.

Sounds like you want GrooveShark: http://groveshark.com

It's a peer to peer program, storing local copies of songs (in an obsfucated format you can't access), so it really needs some kind of local presence.

Why not File API with fallback to Flash?
