What a junk. Every time NOMAD thinks the file is corrupt the OS freezes. The only way to recover is to plug the power cord and go into recovery mode. So if you happen to be out of the house and you have a frozen OS you can't use NOMAD until you get home. After OS froze twice on me in the subway I returned the jukebox.

Ex Output:
Negative


Ex Input:
This album is highly ranked in the metacritics for a very good reason. It's great! If you want to hear fresh and new ways to mix hiphop lyrics and dance sounds you'll love it. Don't listen to anyone who rates this album poorly, it's a top ten of 2005 for sure.

Ex Output:
Positive
