Artists have to pay 120,000 starbits to upload their NFT and then it sells 25 times.

I am not sure if this makes them a profit or not.

My husband is a musician and I am looking for a song my kids and I recorded once upon a time.

I have one of the MP3's ready so I'll be able to tell you first hand if it pays or not.

I suspect that its "for exposure" and fun more than anything, since your song gets played on the rising star radio.
