Blockchain is relatively new and there is room for improvement. The aspect of energy being wasted with NFTs is a thing of the past as 99.9% of the energy consumption needed to create NFTs has been reduced.

I will not deny that there are thousands of scams in the NFT sector, but the music sector is not a category where you see too many scams. If you buy music from an artist (through NFTs) you do it to support the artist and have something special from him.

There is very little speculation with the buying and selling of songs, if you are an artist I recommend that you inform yourself about how other artists are doing it to take into account all the possibilities when it comes to monetizing your work. Although this is just my opinion, I understand that it is something that is not made for everyone.
