Music is eternal.

No matter what music will always be a permanent addition to society, and with music being part of society, people will always want to listen to music, be it Rock, Rap, Dreampop, Shoegaze, EDM, Electronica, Drum and Bass, Country, etc. there will be a group that will be in demand by SOMEONE. Now with popular artists today it is highly possible they go down in history, but that doesn't apply to only popular bands, I can be one of the outcasts that prefer a band no one has heard about than listening to what is "popular". So no matter what, all music will be around for a very long long time.
