Just fyi - none of these things work, and I'm having similar (though far worse) problems with another song...try to navigate to the beginning, won't let me, keeps jumping to a certain spot in the song. As soon as I make a flex pitch edit, it jumps to the beginning, etc. Ultimately, both songs have taken to just freezing when I try to open them, with the color wheel spinning endlessly.
Both songs that this has happened to were originally GarageBand, then Logic 9, then Logic X songs (they've been imported twice). I am having this with no other songs...so maybe there's a clue there.
Logic Pro 10.0.3, Mac Book Pro OSX 10.8.4 (2.8 GHz Processor, 8 GB Memory), Keystation 88 ES, M-Audio Audio Buddy, Phonics 410 Powerpod amp and speakers, various cheap mics
