One all networks Profile vs account
Jamroom Developers
The documentation does not make any indication that it would have to be the JR user. You should be able to link the (social) profiles to a jamroom profile as well.
I hope you see the problem with the current implementation: A power user (label) that has multiple profiles (artists) would be forced to post content from all their users feed to a single profile. So you would never be able to post to the social profiles of the artists.
