Is there an app for shazam? Or how easily could one be made to prompt your phone to open shazam and listen to a song?

Looking for an app/advice on app design to see whether it would be possible to set up a button/app for my watch to prompt shazam to start and listen to music. 

Would be great to be able to do it without having to open your phone. Just wanting to understand If it's a possibility? Or if this has been asked before? If so I apologise but think this might be useful.
