Can’t play music on apple watch using Siri

When i ask Siri to play a specific song on my apple watch 6 OS 10.3.1 ,it simply opens the apple music app but doesn’t search for the song I asked for and doesn’t start playing it. The only solution I have found to be working right now is to ask Siri to play the specific song using the Apple Music app . Only that way does it actually search the song and start playing it.

so pretty much you have to specify which app you want to use every time you ask Siri to play a song through your Apple Watch.
