Migrating away some bard songs

Bard...............................| 17.502 17 3 minutes

Bard...............................| 17.001 17 14 hours, 9 minutes

Bard...............................| 16.999 16 14 hours, 9 minutes

Its underestimating the time by a factor of 2, counting down to 0 minutes half way through the migration and then up again.
