Napster released an app that’s compatible with iPhone/iPod touch/iPad iOS 3.0 or later. The Napster app is free, but it does require a $10/month service. So long as your monthly service is current, you can listen to an unlimited number of songs on your Apple device. You can download songs, albums, or playlists to listen even when you are offline. Napster has Billboard charts back to 1955 so you can easily find and enjoy music from your childhood or any other period. With your paid account, you’ll also be allowed to listen to Napster music on your computer, or on any compatible TV, Blu-ray player, or other home audio product. Of course, you lose all access to the music when you drop your monthly service account.
