The Culture of music in America

Dear reader,
Yesterday we have been to Cleveland to visit the famous Rock and Roll Hall of Fame. I expected a lot of the museum and I really thought it would become great, since we haven't even entered the museum and we could already hear the rock'n'roll sound from loudspeakers in front of the building. I was so excited! We went down the first stairs and I could already see some guitars, which was pretty cool. The atmosphere down there was great! The light was dimmed, so the atmosphere just fit into what the place wishes to express: Rock!
I really liked the guitars hanging around everywhere, since it is in somehow the tool of the musicians via which they express themselves.
The museum was split into parts for different musicians and different sorts of music. I would have preferred if it would have been sorted chronological, but I guess this is hard since the time when bands enter the hall of fame isn't chronological.
The role of American music is being the most important influence in the music of the whole world. America is the leader concerning music, almost all countries just copy musicians or styles, since trends are being set in America. The most obvious point is that the Hall of Fame isn't somewhere in Europa, it is in America.
Musicians are portrayed as heroes because they were a nobody and managed to become famous and have a lot of money without giving up their values. Most of them(!) just do what they like to do and that is something everybody wants to reach. Most people neglect the fact that many many musicians have problems with drugs because they seem to split the life of the musician into their music and the rest of their life, although the musicians themselves won't split that. "I like the music" is one of the most popular phrases in this context, ignoring how the band might live behind the scene.
