Only the Music app is skipping

I am running into an issue. I have cable broadband internet (75Mbps) set up with an airport extreme basestation and an airport express for range extension. Here is the issue I am running into.

When I stream movie from my library, netflix, hulu or even NFL games.. it runs perfect, no stutters, hiccups or anything. However, if I use the music app to stream from my music library it skips horribly.

anyone else having this issue? or know of a solution? I tried to change the streaming quality of the music, but am unable to change those setting anymore.

very frustrating.
