It seems that for 0.1% of customers, the song database gets corrupted for some reason. If you have some problem, please try the following remedies, only going as far as is necessary to fix the problem:
– quit and restart your App (tap home, double-tap home, tap and hold Fairlight in the bottom row, tap the (-) button)
– export your song, then delete it, then re-import it from the export file
– export all your songs, instruments and voices, copy the export files from iTunes to somewhere safe, then delete the app from your device and reinstall from iTunes, then re-import your files.
If all that fails, please submit a bug report in the feedback page, and include your crash logs (see instructions here).
