the level thing on yahoo music what dose that mean?

Answer 1

I assume you mean the rating levels. Here they are:

Rating Master: more than 10,000 total ratings
Addict: 5,000-10,000 total ratings
Fanatic: 1,000-5,000 total ratings
Trendsetter: 500-1,000 total ratings
Enthusiast: 250-500 total ratings
Listener: 100-250 total ratings
Newbie: less than 100 total ratings

You don't actually get anything for being at the different levels. It's just an acknowledgement that you have put a given level of effort into your station.

Answer 2

I assume its the program volume control. Level usually means the level of volume. Most times its independant of your computers volume control.
