Yes, the news that every Spotify customer has wanted to hear. Spotify finally supports multitasking on the iOS4 with the latest update.
You will of course need an iPhone 3GS/4 or an 3rd gen iPod Touch (unless you have jailbroken) to get the multitasking ability.
The new app also supports control from the lock screen and double-click control buttons, which does make the app much more usable. It also features a new “What’s new” section like in the PC application, so you can see the top tracks of the moment and any new releases.
A well deserved update I think.
