In the EDM scene means a remix that was done by an unpopular (usually beginner) artist for or after an event and distributed via their social network profiles. Since EDM is an intellectual property wasteland where any copyrighted sound gets edited one way or another and pretty much everybody famous borrows from somebody else since at least the early 2010, producing a track titled "Me - My song (Somedude Bootleg)" roughly means they want in on the industry as well and want to get famous. Many of today's popular DJs have realeased bootlegged remixes at least once in their lifetime.
"Yo, check out that Calvin Harris remix! Sick, right?"
"That's not a remix, that's someone's bootleg"
"But it's sick still?"
"It's yours, isn't it?"
A remix of a song, almost exclusively in the electronic dance music genre, in which the remixing DJ uses an entire song or samples from a song in a remix without the explicit permission of the original artist. This is however considered an acceptable practice as nearly all EDM DJs care more about the music than they care about the money. Having someone remix your song, bootleg or not, is typically a sign of great respect and appreciation.
