So I was possibly (a BIG possibly) thinking about releasing a free mixtape prior to wanting to release a EP to get a little fanbase going before I release any music that actually costs money. Now I keep reading posts about people who don't know what they're talking about and I'm seeing different answers so I figured I would ask on here: If I used ANY beat (Like anywhere from one of Dre's beats or something that WAS free on soundclick and then someone bought the exclusive rights), this is the point of the questions, would I run into any legal troubles? There would be ZERO profit off of this mixtape. I hope that is clear enough. I ask because my understanding is if you want to record/sell with the beat you must lease/buy the beat, but anything for free like on youtube, myspace, mixtape, there are no problems. Thanks for any info.
