Merged Flow from multiple users

Hi, let me begin this idea explanation by saying how much I love the Flow feature, it works exactly how I would want it to. The only problem is, when traveling with friends, each person prefers their own flow - so it got me thinking about the merged flow.

Technically speaking, it would work like this: one person would select the merge flow option where he/she could invite other users to connect. They would then receive the push notification asking whether they agree to connect. Once users have connected, merged flow would be generated as an intersection of songs if the users have a similar music taste, or as a balanced combination of songs otherwise. (Or both! That’d be great, too.)

There would also have to be an option for all involved users to see which song is playing so they can add to favourites songs they wouldn’t normally get in their flow.

I understand this is not a small feature, but I hope to see it implemented one day. Thank you.
