Don’t unlock mutex that is not locked
Strict pthread implementations (like OpenBSD’s rthreads with PTHREAD_MUTEX_TYPE_STRICT_NP set) don’t allow unlocking a mutex that is not locked, resulting in abort() being called. Always aquiring the lock before unlocking it while skipping to the next song fixes this. Thanks to David Coppa.
