Music from the 80's were great, and there were happy feel good songs. It brought back great memories.
I think it's because of nostalgia and just plain irritation of today's music are large factors into why people feel disdain towards the current music scene.
To be honest I feel the same, I'm just sick of corperate manufactured mass lobotimezed style of music that is pumped out today it's all the same there's no variety. It's just songs about clubs, partying, coitus, love and that isn't to say that those subjects weren't touched upon in music back then, but there was variety if you hated one type of genre - there would be another you could try instead.
But that's the problem today, it falls in the same category barely anyone plays instruments anymore I hate to generalise but when I here the radio and there is someone using a guitar in a new song these days it has no rhyme or rythm, it's just a few notes repeated.
That's not too say the 80's didn't have bad music!
