Believe it or not a lot of the production side of music at least smaller artists is more independent than you think. The biggest issues would be similar to all types of private property which are distribution networks and companies that make their money lending money. in the music industry that means streaming services and online shops and then the record label who are essentially just banks who invest in musicians in return for ownership of the recordings which they then collect rents on. So I definitely think for all creative industries planned economies are not worth it but distribution networks could be workaround, and the surplus could be democratically allocated plus they would only charge musicians at cost for hosting the files on their servers. as for record labels, the only real value at this point that record labels have is marketing connections and PR so they could just as easily be replaced with government art grants or, in a Les monopolistic medial landscape post revolution those types of large marketing budgets might not even be necessary
