Music that always plays on the radio and the TV, and is on the top 40 list on every
music software like iTunes and Spotify. It is quick-made on a computer, usually featuring not very good but good looking musicians (if they can be called that) and it is un-original and boring. People without any taste in
music listen to it because it'
s easy to find and everyone else listen to it, so then they don't need to worry about being considered "different". Mainstream
music songs usually stay on the top-lists for a couple of months or maybe a year, and then they're gone. Also, people who listen to it usually would call a 2 year old song "very old", though bands like Led Zeppelin still
rock anyone's brains out with their songs from the seventees.
