If you are using iTunes as your player (CasaTunes can play music from iTunes libraries and Windows Media Player libraries), the music cannot be DRM protected, so it must be iTunes Plus music or music ripped from CDs or other sources. DRM music in the Windows Media Player library is ok.
[edit 10/12/09]For CasaTunes to play these formats they must show up in either the Windows Media Player library or the Apple iTunes library. Some types of music may require special codecs or other software to show up in the Windows Media Player or iTunes. Due to the changing nature of file formats, CasaTunes cannot guarantee that all features will work with all file formats. For best compatibility, we suggest using formats native to Windows Media Player or iTunes[end of edit].
