commercilized conformist music that is made to not offend anybody. It is listened to in the masses and often is unoriginal. People who don't have a clue about real music like mainstream because it is easy to listen to and it means they don't have to think and can save the effort of their braincells to think about what they should have for tea or who will be evicted from big brother.
guy: that joe mcelderry song 'the climb' is such an example of mainstream music.
girl: i know, that is why rage against the machine's 'killing in the name of' got the christmas number one.

Pretty much the opposite of Mainstream music. Rarely, if ever, gets on the radio or top 40, and it's not usually well known to the general public. Also known as "Underground Music".
