Option to freely raise the subscription fee and pay more to the artists...

For a small streamer, 14.99 might be a lot to consider... But if you're bigger you might want to give more to the ppl behind the music. Wouldn't it be awesome if you could raise it freely? Say, you make the subscription and then have a free field... I want to give xx more to the artists? Another option would be to make it so... that you can have mulitple subscriptions were Pretzel Rocks also gets its share... maybe as another option? Whoever spends more gets no benifits... beside from something like a batch or title that can be used... something like I am a Platinum Member...
