The RIAA has hired programmers to write programs that can sniff out your IP if you download songs, etc.
What bothers me is the fact that they are really ruining the music world.
I used to use Yahoo's Launchcast radio. It was an excellent service but within the past 6 months it has been completely ruined. Now an ad is after
EVERY song. They also limit how many songs you can skip/ban from your list as well.
