I know this is gonna sound wierd but here it goes: Got my iphone syncing with iTunes. I jammed some music onto the black beauty. This is the same library I use for my 8GB Nano. After listen to the music on the iPhone for a while I noticed that some songs sound fine then others sound really low in volume (while the volume is at the same setting it was when the normal song was on) When I listen to the same songs on my nano they sound fine. Has anyone encountered this?
