Anyone interested in this should submit their request via the Share Ideassite. If they get enough of these, there is potential to add Tidal. As for answering the OP's question, not sure if anyone can or will, as Garmin staff doesn't announce their plans via the forums until there is an official announcement.
I'm hoping for this to come out too - I don't want to have to buy an entirely new subscription of music just for running - at the expense of sacrificing audio quality in every other part of my life.
