I have had a problem with the volume level on my iPhone changing. I will listen to one song at a perfect volume and then the next song will blow my ears away, the next song will come on and I can't hear it until I turn it back up. On my iPod Nano I never had this problem and I have the same songs on my iPhone. Since the same songs are on both and my iPhone has the volume problems I have been led to believe that it is my iPhone and not so much the music files from my iTunes library. Some solutions I have tried have been deleting all the music off the iPhone and then putting them back on, which didn't work. Is there anyone else having similar problems? Any ideas on how to fix this?
