An official deal potentially was announced earlier today.
Apple already has licensing deals with Shazam to integrate its music recognition feature with Siri on iPhone and iPad, and Shazam offers best-in-class apps on Apple Watch and iOS (and even has a Mac app).
The app also integrates with streaming music services including but not limited to Apple Music. If the acquisition news is correct and the deal goes through, watching what happens to the existing apps on iOS and Android will be something to watch as Spotify integration is currently included. If Shazam in its current form does go away, SoundHound could be a great alternative for other platforms.
