I’ve been using Tunebite for the last 3 years or so. Normally I don’t spend much time on programs that aren’t free, but Tunebite has been pretty convenient and quite an asset for me. It takes any DRM protected files you have and plays it through it’s Tunebite Player, removing the protection & converting it to a file format of your choice. It’s a great tool to help you fill up your iPod, smartphone, etc. It also works with DRM protected files from Napster To Go, RealRhapsody, etc.
