I like the track length. If you have no patience, then go listen to pop music! I appreciate depth and subtle changes in the music, which can't be done in 4 minutes. Also I'm not a fan of the easy solution: there are lots of tracks where you must endure 5 minutes of ugly build up before you can fully appreciate the 5 minutes of climax that follows afterwards, and I like it this way and fully accept it. Maia is one of those tracks actually: the climax starts around 5 minutes and goes till the end of the track.
Only crappy music is boringly repetitive. And yes there is such thing as crappy goa trance, and no I don't love the genre indiscriminately, only the good releases.
I've listened to a lot of trance and ambient and techno music and they are pretty much all inferior to my favorite goa trance albums. Goa trance has not been ruined for me, at least not yet. Most psytrance is already ruined by lacking creativity and being too hard and sterile. Psychill of the 2000s and goa trance of the 1990s are my favorites and they peacefully co-exist.
I really despise pop music. Artists release full albums, but only 1 or 2 tracks becomes a hit and they get played over and over and over again while the rest of the album is ignored. Even though these hits might have really intriguing climaxes or melodies, they are cheap highs and I always feel dirty listening to them. It's funny and revealing how there is so little depth to pop tracks and yet people still manage to listen to them on loop for hours on end without getting bored.
Classical music is something I haven't explored enough of yet, other than hearing it lots when I was a kid, so I can't comment on it.
