Songs on iPhone sound freaky! But not on computer on iTunes ??

[CountessVonKnackerstein]

Anybody know what this might be?
The songs aren't skipping but there's a funny squeaky sound on some tracks. It's not on the cd, nor on the playback on iTunes, just when I play the song on my iPhone?!

via headphones, the speaker or both?

Just the speaker. Thanks for reply!

sounds like your speaker's knackered then.

No, it's just on some tracks, not all

DH has some of the same tracks on his iPhone and his tracks are all fine.
