Today apple released iOS 5.0.1 to developers to resolve battery issues, enable multitasking gesture for the original iPad and fix some other iOS bugs.
Shortly after the release of iOS 5.0.1 a music section now appears on Apple TV for the new iTunes Match program. However, for the service to work iTunes 10.5.1 beta 2 is required. This beta version of iTunes was seeded to developers today and should be made available to the public within the next few weeks.
iTunes Match will cost $24.99 per year and supports music libraries as large as 25,000 songs. The service will scan your iTunes music collection to find songs that match up with those on offered in the iTunes Music Store. This means very few songs will need to be uploaded to iCloud, only songs that Apple does not sell in iTunes. You can then listen to your entire music collection via iCloud.
