Best XBOX LIVE feature

The votes have come in and the best feature for XBOX LIVE is MUTE.
Annoying 12 year old kids busting your zen like snipe skillz... MUTE.
Some guy thinks he can sing and likes to share it with you. HOMIE DON'T PLAY THAT...MUTE.
Young fellow from the southern us a little too racist for you to knife kill in peace...MUTE.
Gangsters jive talking your turkey...MUTE.

Pretty much the only way you can play COD is with half the gamers on mute.
