What is the lyrics provider? can it be changed as I often get no lyrics found.
Is there a way of bulk downloading lyrics, by album/artist/folder?
Mtouch uses separate text files for each song in the LRC format.
MusicBee on Windows can create those files, but the time synchronization queues are absent unless you manually edit each file to add them.
