During my gyms most recent members night, nobody had thought to bring an MP3 with them to play music while climbing. So we switched to the radio. That of course was a huge mistake, the radio stations here are either new kiddie music, or "The best of the 60s, 70s, and today", which is a lie. However, one member remembered that he had his iPod in his truck. So, we stuck it on and started listening to Frank Sinatra. I personally enjoyed it, and felt I climbed better with Slower Sinatra songs than the faster paced electronika stuff you usually hear.
So, here's my question. Do you find yourself climbing better with mellow music, or a fast thumping bass, or maybe some plain rock? Which and why?
