Baron's audio trigger

Alright, something that has annoyed me for a while now and I thought was just a bug has been here for quite some time, so I can only assume it's intentional.

If you pay attention to the music you'll notice whenever someone(on your team or enemy team) walks near or into Baron pit there will be a piece of audio that goes off in the music that indicates they're at baron. This pretty much contradicts the importance of warding and also disadvantages players who choose not to have music on.

**Basically: Because of this piece of music triggering when people go to baron, players who have music on can pretty much get a free warning the enemy team is trying to take baron, even though they lack the wards to tell. **
