This was the biggest waste of money ever created. If you want to know the song that much, call the station and ask them, they don't mind, really.

Negative

I love my Zen Xtra 40GB - well at least I loved my Xtra. The player is great, except for one major detail - the shoddy quality of the headphone jack. IT WILL FAIL! If you get lucky it will still be under warranty. If you aren't expect to pay at least $40 for the clowns at Creative to fix it. If you think I am just flaming them, check out their forums.

Ex Output:
Negative


Ex Input:
