Music stops playing partway through and skips to next song in iTunes and on iPhone
Recently I switched from an old macbook and an iphone 3g over to a macbook pro and an iphone 4s. I transferred my library from my old mac to my new mac.
After the switch I was listening to music in itunes, and found that many songs play completely regularly until about three quarters of the way through, and then they skip to the next song. This occurs with purchased music, music off of cds, and digitally downloaded music. When I play one of these messed up songs, and then skip to after about three quarters of the way through, it just skips to the next song. Its as if the data for much of my library's songs, is missing for the last 25% of the song. This isn't a problem with start and stop times, as I checked all of them, and they are all as they should be.
I have found a similar problem on my new iphone 4s. The same songs that are messed up on the computer are also messed up on the phone. The phone will play the song regularly up until the same point as it plays on the computer, but then the audio stops. However, unlike the problem on the computer, in itunes, where it skips to the next song, on my iphone, the audio just stops playing. The audio is missing, but the iphone appears as if it is playing the song regularly (it doesn't skip to the next song, the music isn't paused, it just plays along with no audio).
Any ideas?
