Attention:
No one cares what you listen to.
No one cares that you don't like Opeth.
No one cares who you think is the best metal band ever.
If you don't like Opeth, don't engage in Opeth discussions. I have alot of good friends who like Opeth and Dream Theatre, but I don't bring it up on a regular basis how much I don't like them, and I usually stay out of any conversation anyone has about them unless they are asking me directly my opinions.
Why do people think Opeth is great? Because they like somthing different. Why do people like punk, pop, hip-hop, Jazz, Classical, Rock, Techno, Industrial, folk, ect.
I hate Slayer. I gave them a good try, I even have 2 of their albums becuase I wanted to like them, I was told they were the band every metalhead loves. I hate them. I like Thrash, I hate Slayer. But I don't start a thread about it, becuase its just asking for an arguement. Its asking for someone to go "shut up Slayer rules".
Stop being an attention whore plskthx.
