I'm not so sure it's wise to call G+ a "dead" social network. According to recent research by Pew, it's more popular than Twitter and just as popular as LinkedIn.

If the numbers there are right and only 4-6 million people are using it as a social network it isn't very surprising that Google would be "giving up on pitching Google+ as a social network"

Every time I want to create a new playlist, I create a new G+ profile, then delete it immediately afterwards. It is tedious. I'm sure many other people, when faced with roadblocks like these, create a do-nothing profile but don't bother deleting afterwards.
Or don't use playlists and find other websites.
Just sayin'..
