Apple has finally convinced all the big labels to release their music as DRM-free ‘iTunes Plus’ tracks at the same 99 cents. Like prior iTunes Plus tracks, all music will now be sold in DRM-free, 256kbps AAC format. Starting today, eight million songs are available; all ten million songs are expected to be available DRM-free by the end of the quarter.

iTunes will offer customers a simple, one-click option to easily upgrade their entire library of previously purchased songs to the higher quality DRM-free iTunes Plus format for 30 cents per song or 30 percent of the album price.

Apple also announced the new capacity for iPhone 3G users to download songs over the 3G mobile network, in addition to the WiFi downloads that were formerly the only way to access iTunes from the mobile. There is no extra charge for downloading tracks over the mobile network, as there is with some other services.

Beginning in April, and based on what the music labels charge Apple, songs will now be priced at one of three price points—$0.69, $0.99, and $1.29, with most albums still priced at $9.99.
