End-game music in Matchmaking?

Was jsut wondering, why is this in for gametypes like SWAT and, presumably, Snipers?
Without a radar, the only thing we can go on is the sound of other peoples footsteps, which 343 have obviously acknowledged by putting in a specialization to muffle that noise. So why, with 5 kills to go, do they let music play?

Maybe if it were just strings or something, but with percussion it just makes listening out for enemies almost impossible.

Thoughts?

Eh, to be honest it’s never been an issue for myself. I have a Surround Headset, so it’s a minor problem for me at best. Also, Swat is kind of dull this time around. The Battle Rifle completely dominates the playlist.
