There's nothing abnormal about that. I don't blame you, 99.9999999999999% of music is complete and utter trash. I hate this stupid pop culture and all the music associated with it. I hate, hate, HATE chart music that plays on these really annoying stupid radio stations like Kiss fm and Heart fm which are hosted by dumb inbred chavs. We're constantly bombarded with trashy music playing from trashy radio stations, it's very hard to avoid music nowadays. Whether you're in a supermarket, a gym, your workplace, or even at home, you're always going to be exposed to music no matter where you are and you'll have to suffer and endure all the trashy music that surrounds us nowadays.
You certainly don't need to listen to music. Nobody does. It serves no other function other than to entertain. It can be nice to listen to some songs if you're bored or whatever.
I completely agree with you when you say that true freedom is to live without music. Unfortunately, I'm much too dependent on music personally, it's a problem I wish I didn't have, but I do love me tunes. The selection of music I listen to is extremely narrow, I think my whole music collection consists of just a couple hundred songs or so literally. But even though there's no variety and it's a really tiny selection of music, I'm pretty much always listening to it and have done so for many years, wish I can stop but I can't. It's very restraining to be this dependent on it. Being somewhat of an audiophile, perhaps I can put all the blame on my audio equipment, it certainly enhances the experience in a very huge way.
But I definitely agree with you when you say music isn't extraordinary. The lyrics are always meaningless, music doesn't ever carry any sort of message, it's just for entertainment purposes. Some people like to go out for walks, some people like to play sports, some people like to socialise with friends...and some people like to listen to music. But I have to say, I really really HATE all the mainstream music that I hear on tv/radio/internet these days, complete trash and extremely annoying, I wish it would stop.
