Congrats Peter, that's excellent news.
I'm sure you have some excellent updates scheduled.
Here are a couple of suggestions for updates as you see fit.
It would be great to be able to Copy and convert a Lyrics Only song to a Multitrack version (simply to make for a more convenient and time effective duplication of the same song.
Also, it would be exellent to see a "snapshot" of what playlists a particular song is on from the settings screen (as opposed to having to click into the next layer to see if a song is assigned and on what lists).
Just some thoughts.
