Damn, that sucks. I think you DO have the grounds to sue, if you have proof that it was your project (and by proof I mean something that can convince anyone who sees it, such as the project file. I personally believe it was yours). You might be able to get some money out of them for copyright infringement, or at least get them to remove it from that compilation, if you can find a lawyer to take it on.

"It was actually first processed as a dubplate special since it was originally unreleased for the genreal public. And it did cost some money even though it was originally not yet produced on vinyl. Later, once I got it pressed, it was then mass-produced on vinyl. Pretty interesting process, and a little costly... $1,349."
Ahh, cool! I'd assume you had the backing of a label when you got it pressed, dare I ask what label? If you did it yourself, then how did you hand the distribution?! O.O
Sweet. Vinyl rocks. If only there was a few more minutes, maybe with a straight kick on both ends, I'd try to work it into a set (I DJ with mp3s). Too bad it's gone now :(

It was actually going to be done through Tunnel Records at first, but before I signed the terms of agreement for distribution, I decided to go with an underground label Blue Martin Records since it was a lot cheaper like hundreds of dollars cheaper. But, for some odd reason Tunnel Records decided to take it upon themselves to use my "Orbital Trance" at the time under their name even though I never technically agreed to them taking rights for that. It's totally unchangeable now. :-(
