So i had one track off of the album with teeth by nine inch nails in my library, and thus on my phone. the track plays FINE in itunes. but when I play on my iPhone my phone freaks out, it locks up for a good 30 seconds and never plays the song. So today i finally got around to deleting that MP3 from my library, and replaced with a NEW mp3, as well as a few more songs from the same album. Again, they all work fine in itunes, but now i just synced them to my phone and it is doing it again! it's very frustrating and ONLY happens for those songs. Any ideas? Thanks for reading.
