BrawlBRSTMs3 is a YouTube channel where a lot of extended video game music were uploaded. You could probably recognize it by the fact that it didn't have an avatar and a channel banner. Now it does though, since the channel got hijacked a few days ago by the hacker - he changed all recovery options, so the original owner got locked out completely. Now the account is being monetized by the hacker for his personal gain - you can seeY ouTube's verification mark after the channel's name.

So yeah, while the old channel is hacked, the original owners started a new one called SmashDSPs. New channel has 1 hour uploads and over 9000 seconds for final boss themes.

As the original owner said, don't support BrawlBRSTMs3 anymore, and don't let the thief enjoy his "victory."
