Incoherent simfile's #MUSIC behavior

[florczakraf]

There's variety of packs out there in the wild that have inconsistent metadata like in the case below that comes from Bangers Only's Ballin', where #MUSIC states a name for a song file that doesn't exist:

Technically nine-or-null does exactly what it's told to do, but it fails silently, while the game plays such simfiles correctly. The biggest issue is that one can miss a song when they run nine-or-null for the whole pack because there's no indication in the UI that something has failed and the list will be partially filled.

Full log in text form for better indexing:

good call - I would like nine-or-null to have the same default as stepmania (although it's a little frustrating that a simfile can be made without explicitly pointing to the music).
