Can't listen to an entire song in Itunes. Randomly just skips the song in different places while it's playing. Song file is not corrupted - even doing it on a new song I just bought from Itunes today. Help :(

Question

I just bought a new laptop and transferred over all of the songs.  But I checked the ones that skip in Itunes in another music player and they work fine there - the files are not corrupted - and like I said, even a brand new song I just bought skips.  The priority for Itunes is set to High.  This comptuer has very high specs (it's a Lenovo IdeaPad) and the processing performance never even goes above 10%.  I am a Disc Jockey and this is a severe problem.  Please help...
If downgrading to a previous version of Itunes is the answer, how do I go about doing that?   I'm currently running 10.5

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.
