I wanted to buy unlimited licenses for two beats from a producer. One was on beatstars and the other was not due to the producer not having the stems. The beats were buy one get one free. We discussed that once I bought the one on beatstars he would send me the second beat for free. Of course now he's been dodging my emails and acts like he forgets our discussion though it is all documented in email traffic. He has yet to send me the .wav file I asked for and this is going on two weeks. From a legal standpoint, can I move forward with the beat with unlimited license use? We don't have a contract, but it is documented saying he would send me the beat.
