Hi Ben,
First off, Happy New Year :)
Personally i have similar feelings about music in respect to spotify, youtube et all.
As i only just start out to release my own music, i was pondering whether i want to use bandcamp or a similar platform to release mmy music.
Yesterday i stumbled upon steemit, singed up for it and today your post caught my attention.
Being a freshman here on steemit, it will take me some time to find my way around here.
I'll send you a mail and hope to get some more info about @steemsongs from you.
As for AI replacing music makers, i think that areas where it might replace music makers in the immediate future are in music for advertisement, jingles at first.
Later on i think that AI might take on also movie intonation, soundtrack and sound effects.
For AI to create songs, no matter which kind of musical style, will be another level to achieve.
Main reason imo is that AI is still not capable to have emotions, feel emotions, which music/songs is/are all about.
AI is perfectly capable of creating melodies, harmonies and rythmic pattern variations, swing, yet AI is not capable to comprehend/feel what emotional impact that has on themselves resp. on the listener.
Hence i think that AI created songs will sound AI made, like a drum machine will always sound like a drum machine.
I won't put it past spotify, google and the music industry giants to release AI produced music, but it will never match human made music until AI i capable to perceive emotions.
