5 minute song is cut to 2 minutes and 30 seconds?

I'm not really sure what's causing this, but basically whenever I try to play "Unknown Artist - Comedy Tonight" from A Funny Thing Happened on the Way to the Forum, the player plays it for 2 minutes and 30 seconds.
I've checked the settings page for the song's metadata and manually adjusting it doesn't seem to do anything.

Quick follow up, this is actually happening with all my songs in that album... this is really confusing.

What format are the files?
Have you tried playing them with another player?
