Okay. I hope you understand that when rewards are involved you have to be very clear about whether it is an original work. I contacted the artist and she was not happy about her work being copied like this. I think it's a little different with music as it is generally obvious if it is a cover.
Just bear this in mind. It would be better to do something original anyway. I do post my own music too.
Hive can seem strange at first. Please do not be put off.
