I don't know much about Karmatronic, but from their injection of pure adrenaline into the #1 iTunes download at the moment, Train- Hey, Soul Sister, I clearly crave more. I feel like I'm in a Soho loft blasting this song at an after hours party but in reality, it's serving as the soundtrack on my way to work in the morning. Nonetheless, this will clearly be on repeat come Friday night.
