Comes with Spotify. Spotify hits S60, a little while after iPhone / Android. And it’s quite sweet, the iPhone version suffers from no backgrounding/offline storage/the total lack of O2 data in central london.
Oddly the S60 5th edition one uses ONLY a t9 keypad for text entry, though I presume a physical keyboard (like the N97) will work ok. which makes the interface a bit clunky, but it works a treat with my t-mobile sim / web-n-walk. I’ve only had a quick play with it and not tested its commuting abilities yet.
Just go to http://m.spotify.com on your phone to get it, you need a premium spotify account.
