This is the 1st time i've ever read a thread and thought, everybody is spot on.
I really like what HHC and lacoste said, I have similar thoughts there.
I appreciate all music except that which is used for manipulation in a bad way, for example music with subliminal messages which have been used in the past, for an example I can remember, do any of you remember an episode of The Simpsons where they used subliminal messages in music to recruit soldiers for the navy? YVAN EHT NIOJ! (This is an extreme and obvious example, and it's a cartoon so not real, but it has happened in the past and does reflect this.)
There has been evidence of hidden messages in music in the past, I haven't really done much research into this so not sure if it's a big thing these days.
However, I do appreciate subliminal messages in music in a positive manner, for example spiritual stuff with a positive vibe aimed to make the listener feel at ease and relaxed, self-help music as well.
Also, it's a 50/50 opinion I have for hand picked bands with extremely good looking people designed specifically to sell sex and make money, I hate manipulation and the fact people are so easily swayed and attracted to this kind of music, but at the same time, it makes a lot of people feel good and have something to aspire to, it can make friendships and amazing experiences in life for people. I could only wish that the money was distributed more fairly, rather than the managers and people like Simon Cowell who make ridiculous amounts of money, if it went to charity to help struggling families or cultures i'd be much happier with it.
I used to be a horrible person for this kind of thing, if I didn't like something i'd get angry and tell the person it's bad, it sucks, you are stupid for doing it etc, I hate that part of me in the past, i'm much more open now, if somebody likes something and it makes them feel good, and they aren't harming anyone in the process, wtf does it have to do with me if I like it or not?
Music itself has helped me realize this and grow as a person. So I have to say i'm learning towards mainstream music being more good than bad, there are some problems with the music industry, some corruption, manipulation, abuse etc, but for the most part music is a beautiful thing
