In some cases, al that you said might be true. Where I think differen from you is abot the "No turning Back" part. I play bass, so if there's something that shows the bass players are good, I like that band, i.e.: Jamiroquai, Mudvayne, Rush, Primus, RHCP, Dream THeatre, Stu Hamm. If we listen to metal bass players, there are a few bass players that you can say "He's talented" i.e.: Death, Children of Bodom.
Besides, I'm very open minded. I don't listen to britney, M2M, N'sick and stuff, but I like Jazz, Classical Music, Thrash, Funk, etc.
The cool thing about metal (IMO) is that makes you feel different. and has a lot of variations. Are U sad?: Lacrimosa, Lacuna Coil. Melodic stuff? In FLames, Dark Tranquillity. etc. So if you are into DeathMetal, you have a lot of variety where you can browse the music you like most. But, in my case, I usually get out of the metal stuff when I want to listen some other stuff.
