I love singing and will do it almost anywhere, but it's like what's been said. I just try to emulate who I'm listening to. I usually end up with a lot of the higher-pitched rock songs of the 80's. I end up killing my voice trying to hit as high as some of those singers like Freddie Mercury, for instance. I think I might have caused some internal bleeding trying to hit that high note in Bohemian Rhapsody. Steven Tyler, David Lee Roth, Michael Jackson, Brad Delp, and Jon Bon Jovi all sing songs that strain my voice.
One singer I try and constantly fail to sound like is James Hetfield. Metallica's fun to sing with when I'm mad, but I can not sing like him no matter how I try.
