Mitchel Broussard, writing for MacRumors:

Popular music-detecting app Shazam today rolled out an update that adds support for the service within Messages, so users can send new artist and song discoveries directly to friends and family members.

The only user interface option within the Messages app for Shazam is “Touch to Shazam,” so whenever a song is playing nearby, allow the app to listen and once it does it’ll create a card to send to the current contact. The created message can be tapped on to jump into Shazam, buy the track on iTunes, or listen to it on Apple Music.

This is clever: if you’re in iMessage and want to share a song you’re listening to, you don’t have to go look for the Shazam app. Between iMessage and interactive notifications, I like what Shazam is doing with iOS 10.
