being on the treadmill at the gym and my pandora station either 1) loses connection so I get silence 2) start playing slow music on my hardrock station. The area I live in is pretty bad for both radio and wifi connection, so I can excuse pandora losing connection- as annoying as it is. But I listen to hard rock because it has energy that helps keep me going, and it's hard to skip the song because then I get advertisements and if I can't skip too many songs. Some of these songs I do like, but not when I'm trying to stay on a treadmill.
