Some (few) may know this, but I have access to vast quantities of royalty free electronic/dubstep music. And I will now reveal the source of it and a couple good artists to the entire community.
This is the website where it all comes from. Those familiar with the mobile game Geometry Dash should recognize this. Newgrounds
It’s a somewhat sketchy (ske7ch-y (I couldn’t resist)) website, but there is SO MUCH STUFF on it.
Lots of the stuff on this website is free to use. Beware there are some knobs posting copyrighted stuff that they didn’t make (If it’s by Skrillex, it shouldn’t be there).
Some good musicians to check out:
Waterflame - I do believe 90% of his stuff is royalty free (some OST stuff isn’t… I think)
Boom Kitty - I believe also copyright free
Mafia Pineapple - I’m not totally certain here… If you want to use his songs, send me a message. I am in contact with him.
Some of F-777’s music is also copyright free. Contact him to find out more. I think he’s a bit stricter about this stuff.
Also: MDK has a ton of great songs and they are pretty much all copyright free. Fans of Legundo should recognize MDK (Legundo uses MDK songs in his intros).
DISCLAIMER
If you get in trouble with anyone for using their music without permission, I am not to blame. I have posted these links as sources for you to explore. Please contact the artists or ensure that you can legally use their songs before creating anything with them.
