Well, music is my life. It's changed a lot about me & opened my mind in many ways, likely even in ways having nothing to do with actual music. I've made great friends based off our similarities in music taste. At the same time music has made me not care what people think of me. My music has set me apart from all the people here who drive around blaring 50 Cent & Beyonce through their subwoofers. I only know two people here who listen to Metal, & anyone else I will play my music around at any time, regardless of if they don't like it (well, I will be nice sometimes, I'm no asshole, but I won't listen to something I hate especially while driving). When I first got into Yngwie Malmsteen he totally blew my mind & changed my approach & technique applied to the guitar. I probably was about 15-16 when I got into him. In the years to follow I broadened my tastes, & it made me a different person in a lot of small ways. I virtually spend all my free time doing things that relate to music, be it listening, watching, or playing.
I definitly think music can change your life, it did to mine. Without my current tastes I would be a different person, & so would most people here. I can tell that music plays a major role in a lot of people's lives here.
