Challenge 16: Your views on mainstream music

Mainstream music denotes music that is familiar to the masses, as for example popular music, pop music, middle of the road music, pop rap or pop rock: Mainstream jazz is generally seen as an evolution of be-bop, which was originally regarded as radical.
Opposing mainstream music is the music of subcultures. This exists in virtually all genres of music and is found commonly in punk rock, indie rock, alternative/underground hip hop, anti-folk and heavy metal, among others. In the 1960s this music was exemplified by the music of the hippie counterculture.

Yeah so mainstream music is..okay..nice...don't really have an opinion about it!
