the big majority of brazilians listen to shit
like
Musica Sertaneja (really bad country-like music with depressed or perverted lyrics)
http://pt.wikipedia.org/wiki/M%C3%BAsica_sertaneja
Pagode (really bad simple samba-like music with perverted and cynic lyrics, but it was a good genre until the end of 90 decade)
http://pt.wikipedia.org/wiki/Pagode_%28m%C3%BAsica%29
Funk carioca, well... think in the worst music with the worst-dirty-disgusting-perverted lyrics ¬¬ and the parties that have funk(carioca) are group-sex-like... very worth of vomit

and for the young people, there are always the emo/punk, the metallers/gothics, the hip-hop/rapers and the dance-music/mainstream-american-pop-music lovers
those that listen to classic stuff are really very few people (generally people with more than 40 years and a good education/money)
to have an idea, there are more persons that listen to mainstream japanese music/animesongs than persons that listen to old brazilian classics in Brazil T_T
IMO because of bad musical scene the young people doesn't research about old stuff and are disapointed with brazilian music in a way that makes they even doesn't want to hear about it
for example, my bf likes metal, medieval-like-music, classical, 50/60 pop stuff(like SR XD), jazz and animesong. And when I try to take him into the classic brazilian stuff at 1st he is like "BLARRRRGH brazilian music!!!!! X_x" and after "o.O hmmm sounds interesting... mm relaxing"
I think there are good new brazilian stuff... but I don't know where, cause they aren't popular. if you want to find you need to search (unhapply I don't have time to do anything at the moment, so I feel guilty saying that "THERE AREN'T ANY!!!!" >_<)
I pointed potuguese articles on wikipedia cause they are more complete, the english one that I pointed is (don't know why)more complete that the portuguese one. And I join emo with punk, metal with gothic, and etc cause the people who heard the 2 genres that I join are only one group of peoples.
