Ask HN: Any tools for two way synced music listening?

One of my work mates and I used to use the Soundrop app in Spotify to have a synced shared playlist. We grew up together and have similar tastes in music and its fun to occasionally talk about a song or share new stuff with each other. He is on the other side of the country from me. Is there any other options? I've tried the few obvious ones that come up when Googling but none of them are as seamless and simple as I'd like. Does anyone else do this? Any awesome solutions that you've come across?
