I would have done iTunes... but that list has THOUSANDS of bands. Some of which I don't really listen to that often.

^that is A LOT of bands

And yet no one ever believes me whenever they ask me what bands I like and I say that there are way too many to list.

im the same, i just put the first few that come to mind because first of all, monstercat alone has a TON of artists

Taylor Swift
Lady Antebellum
Carrie Underwood
Whitney Houston
Simple Plan

And I prefer songs that came from movies like Lady Gaga and Elton John's "Hello hello" from Gnomeo and Juliet

rap wise; kedrick lamar, a$ap rocky, jay z, immortal technique, biggie, nas and odd future (actually not really odd future because most of them suck. tyler, earl and left are good tho.) other stuff wise, mostly noah gundersen, the courage, gaslight anthem and against me. also this local connecticut called bonsai trees.

By "left" are you referring to Left Brain? Because if you are then you literally have no fucking clue what the fuck you're talking about because he's a producer, and raps occasionally as a joke...

P.S. fuck The Gaslight Anthem.

@Chuck Finster OMG...Do you listen to music 24*7?
