I'm somewhat in the middle on this one. I do like some older music, as well as newer stuff. I don't particularly care for a genre as a whole, I listen to what I like... just happens that a lot of stuff I listen to, does fall into a somewhat same category.
However... I can't really have most pop songs. Or popmusic for that matter. I don't know... it just strikes me as soft, overproduced and not raw enough. I think that's what's for most the mass appeal though. I remember... and I wasn't there firsthand... I'm not that old! but... in the 80's when there was a lot of hard rock bands and people thought "oh my, this is heavy stuff" and along came a band like Slayer, which went into overdrive as means of intensity in regards to contemporary rock music from the early to mid 80's. I, myself have the urge to always enjoy the bands and/or artists, that push that limit by any means. If it's either intense, over the top ridiculous technical or just really odd inventive, it seems to stick for a while. It's not even that I want to state "I'm a tough guy, look at how heavy and intense the music I enjoy is" but a lot of soft stuff doesn't stick with me. Some stuff I give listen, even a 2nd one. I still listen too some 90's hip-hop & rap, quite some alternative stuff from there... that's probably a bit of a nostalgia & memories thing.
The reason I enjoy a lot of dubstep currently, it because it's stretching the boundary of how low can a bass drop without bottoming out... it's a rather techincal thing actually. But apart from that, I like some tunes in that genre.
With the entire plagiarism thing, there's a couple of things that come to mind.
a. There is a lot of overexposure of artists due to the internet. No wonder we hear a lot of music which might or might not be intentional copied.
b. At some point combinations of melodic arrangements are used up... and stuff begins to sound off if you try new combinations. Depending on how "off" it sounds, It might eventually stick to a lot of people.
c. If something works, it seems that they apply the "don't fix what ain't broken principle"
d. Some stuff applies as a blueprint for a said style. After hearing 10 dubstep songs, they all go "wobblewobblewo-wo-wo-wo-wobble-DROP-Bigwobble". But that's what that kind of music does. Nothing more nothing less.
e. People have a hard time to differentiate songs. I've had people tell me "well, all these guitar solo's sound the same" but in fact, they're in a totally different scale, and totally different notes.. some people don't recognize notes that well. Some people told me "this sounds a lot like this and this song" and I didn't think so... and the other way around.
