It would be awesome if you could add an album text field to the song editor and then make that a searchable item? In our church we try to be as specific as we can about which song we are singing. We try to tell our musicians the song name, author, year, album and even the song version (in case there is an acoustic version for example). That we when we show up for practice, there is less chance that someone will have learn't the wrong song. Having at least the album text field would be really helpful for us and I'm sure, many other users.
