Well Paranj
lemme tell u ..evryone has got their own taste
So when my frnds say "ye kya dhai dhai sunta rehta hai ? " I say to them F**k you
Only some people like us have the power to enjoy the beauty of metal whatever form it is Death, industrial, Nu, Black, Thrash etc etc
I am a big big fan of Rammstein

..Just listen to them ..read their lyrics translation frm herzeleid.com and u will feel in heaven..Read my blog *musicworld15.blogspot.com for more recommendations ...
but I dont listen to metal everytime..I listen depending on my mood. I listen to every type of music like love songs ,ghazals (Jagjit, Ghulam Ali, Mehndi Hassan),kishore da, Mohd rafi, hindi,english,rock,pop, spanish and german music
I mostly listen to metal when I am feeling angry/depressed/frustrated or sometimes I wanna
My choice of Songs :
1. All Rammstein songs
(Spiel Mit mir, Feuer Frei, Engel, Du reischt so gut, Mein Teil, Heirate Mich etc etc)
2. Hallowed be thy name (Cradle of Filth)
awesome when church bells chime..and all the screams ..eeeeeeeee
3. Iron Maiden like Fear of the dark, The Phantom opera etc etc
4. Dirthouse , Speedway by Static X
5. Chaos AD by Sepultura
6. Metallica songs like cyanide, Sad but true, The God that failed etc etc
They rock !!
and ya IronMan has given lots of valid and hillarious reasons that why Metal is not main stream..
IMO the reasons :
1. Not everybody has the patience and power to listen to this genre

2. Metal is considered as Anti Christ
3. Its considered loudest music which ordinary ppl cant understand.
4. Listening and headbanging to it ..can break ur spine and head

5. It contains the most violent and gory topics like blood, g*y, incest relationships, cannibals etc etc so most ppl stay away frm it (although they dont understand lyrics)
6.Its considered as sign of distorted violent mind by Junta so...
But if u get addicted to it..there is no stress reliever like Metal ...
Hail METAL
