Apple today announced the launch of its iTunes Music Store, a new online store that lets customers quickly find, purchase and download the music they want for 99 cents per song, without subscription fees. The iTunes Music Store, which is integrated with iTunes 4 (also released today), offers “groundbreaking” personal use rights, including burning songs onto an unlimited number of CDs for personal use, listening to songs on an unlimited number of iPods, playing songs on up to three Macs, and using songs in any application on the Mac, including iPhoto, iMovie and iDVD. The iTunes Music Store features over 200,000 songs from music companies including BMG, EMI, Sony Music Entertainment, Universal and Warner.
