I thought a system like m-TAGS would be a nice way forward, as to seperate the audio file and ID3 tag into two files. http://www.m-tags.org/
It'd mean that the tagging standard could change but the audio file would remain the same as long as you don't modify it for whatever reason.
I guess I also believe that plenty of platforms with user-generated content have boundless stuff to see, and making the platforms themselves responsible for recommendations gives them almost too much responsibility. I understand it's part of the business plan, but recommendations would become less toxic of a phenomenon if they weren't forced onto your regular user experience as you engaged with the platform.. and better if they were more individual and something you'd have to access separately. Like movie reviews in the paper!
