I’m pleased as punch that a pal of mine introduced me to Songwhip – a super convenient website that’ll ingest music links from a wide variety of services and websites, and provide a centralized URL for sharing. Friends sharing links from Apple Music, but you’re a Spotify user? No problem.
Just take this lil’ linky-link to Mark Ronson’s cover of Just, by Radiohead:
https://itunes.apple.com/us/album/just/259214420?i=259214652
Paste that into Songwhip’s search field, and get a slick little page and URL in return:

From there you can hit Spotify, Amazon, or wherever you might find the track/album/whatever. It’s not perfect, and there are some quirks, but I’ve found it to be a great way to share music with friends across a broad specturm of streaming services.
Where this has really shined, in my personal experience, has been integration with Slack. One of my (too many) Slack teams has a music channel, and the Songwhip integration will echo out their URL whenever a song/album link from a compatible service is detected. Coupled with disabling autoexpansion of previews for services like Spotify, you get a nice neat sharing experience:
