Meta-song that could be a disaster...or a munchkin-maker

[Scrambler]

It's been bugging me for a long time, but how would Doug's metatalent interpret "the song that never ends"? One idea is that the next song he plays, he gets stuck with that power for 24 hours, unable to access any other ones. Obviously, the most sinister version would cause a permanent lock-up on his metagift.
