i think you are forgetting some points that have already been made, Mac profited off Finesses track through DatPiff!!! Copy Writers can go after Any1 who profits, even if 99 Cents was made off a track...
Going after DatPiff as a distributer is different, since part of their Terms of Service agreement absolves them from any copyright violation that may arise from people uploading material they do not own the rights for. Even if they profit off of advertising through the download, they make it clear that they are an upload service and that the liability lies with the artist who uploads infringing material. If DatPiff was named, then it would be a landmark case, but Mac being named is not a landmark case at all - it has happened before and will happen again.
So any rapper that ever did a jackin for beats could be sued the sh*t out of right now? Bullsh*t. I remember Deadmau5 was bi*ching at Nick Cannon for rapping over one if his tracks then proceeded to tell Nick that he "didnt know the business". I would lawyer up and take Lord Finesse's project apartment
Are you saying that Finesse could be sued by Mac? No. There is no case for that to happen.
And yes, any rapper that records over an instrumental who does not give proper credit to the right holder can potentially be sued, it is just that most rappers doing this who are worth suing either get permission or at least give credit to the right holder in the first place, making it nearly impossible to sue since it would be viewed as mutually beneficial - since if you have the right holder in the liner notes, then the courts will a.ssume that any promotion the artist gained was also given to the right holder. In this case, Mac did not do it legally. This is not some landmark case, stuff like this happens all the time, and is usually quickly settled out of court because Finesse really has a pretty open and shut case. What IS up to interpretation is the financial liability that Mac owes to him - in this case like all infringement cases you shoot for the moon and settle on pennies on the dollar so the infringer can avoid a costly legal battle and a possibly high settlement. This is just how the copyright game goes, and Mac really should have reached out to Finesse in the first place, or AT LEAST gave him proper credit. Why is it such a hard thing to give people credit for their instrumentals? Doesn't Finesse deserve to be credited? If I made a beat and someone went over it without even citing me legally in the liner, you better believe I would be suing them if they blew up and made a career off of my beat. That is only fair.
