Spotify tops the charts for multi-platform support

My T-Mobile SIM is currently residing in my cyan (blue) Nokia N9 and the hardware and slick OS are keeping the device in my pocket and out of my bag. There is an official Spotify app for MeeGo on the N9, but I prefer to use the 3rd party MeeSpot client that gives you a simple tap and hold option on a playlist to listen to that full playlist. You can also sync music for offline listening and even scrobble music to Last.fm. Spotify also just launched this week on Windows Phone 7/7.5 and it looks beautiful with the Metro UI fully integrated.
I was using Zune quite a bit, but that is limited to Windows Phone and streaming through a computer web browser. Slacker Radio was also one of my favorites, but there is no MeeGo client and the Symbian client constantly stutters when trying to do more than just listening to music. Spotify now runs on the following platforms, with dedicated clients for each:
- Windows XP/Vista/7
- Mac OS X
- Linux (Preview build)
- Windows Phone 7/7.5
- Windows Mobile
- iOS
- Android
- BlackBerry
- MeeGo
- Symbian
- webOS
I questioned if Spotify was the best mobile service when it launched and I was critical of it not having a radio or easy discovery method like other services. However, the integrated Facebook support with easy sharing of playlists has convinced me with just a bit of playlist setup the service is excellent.
