I'm going to mention a couple of names. I'm not giving them links, but you can Google as well as I can:
Roy Zimmerman. What the fuck?
George Hrab, knockoff of Roy Zimmerman. What the FUCK to the power of WHAT the fuck?
Look, I like being pandered to as much as the next guy, but seriously, in public: if you can't sing, don't. If you can't write lyrics, don't. If you can't play the guitar, PLEASE GOD do not.
