I hate to do this.........but here goes nothing.
Name one genre of rock, which is not.
First, the comparison is not between METAL and POP, but between METAL and other rock genres, which are equally "metallic" (eg. Grunge/ Punk/ Acid/ Industrial/ Death/ Thrash among others). Second, no self-respecting rocker would compromise power/ lyrics/ chord to MELODY as in pop.
Again, aren't these technologies. And once again, which rock genre doesn't use a mix of these equipments.
Most of the rock genres can trace its roots to all those (including folk/ blue grass and dare i say jazz)
So, u can see, u have only given a vague def of metal, which can be applied to any genres of rock. Again, answer this and u will find your smiling face on the cover of Rolling Stones.
Differentiate between METAL/ GRUNGE/ INDUSTRIAL/ PUNK.
After over 2 decades of listening to a wide spectrum of rock, you will be asking yourself the same question. What exactly is the basis for categorisation. Is it the sound, is it the vocals, is it the arrangement, is it the philosophy, is it the background of the band......what is the basis.
Hope to see u there someday................
