More Music Apps Join The Background-Enabled Party

While Pandora got the top billing when Apple demoed iOS 4 multitasking, other music services are also updating their apps to support background play.

Multitasking in iOS 4 allows compatible apps to run in the background while another app runs in the foreground. Apps in the background can continue to perform tasks such as play music streams.

Slacker Inc has announced that its personal radio application, Slacker Radio, has been updated to support multitasking and is available now for free on the App Store. The currently Europe-only Spotify is also headed for background-centric adjustment with the company announcing on its blog that an update has been submitted to Apple. The blog post goes on to suggest that a “surprise” will also be included in the update to thank users for their patience.

As well as music streaming, GPS navigation apps and social networking clients are also popular background enabled apps. Expect to see many more updates of this type in the coming days.
