Assistants love only controls and searches currently open music app.
If using spotify, with all other music playing apps not running in the background, assistant love only searches in spotify. If you are using the music app/iTunes match with no other music app running in background, then Siri only searches iTunes Match. As it works now, if you search for a song and want it to play in spotify, if you have that same song in the music app then the presence of the song in music overrides a search in spotify. Basically a setting for assistant love/ Siri to control and search a single open music app would be ideal! (An example of the problem: "Siri play frank ocean." I want Siri to open spotify and play the Channel Orange album. Instead, since I have a Jay Z song featuring Frank Ocean in iTunes Match, that song plays instead.)
This is a really good idea. Expect it to pop up in a beta soon, beta repo is at http://getdelta.co

I really like this idea, wish I had thought of it earlier!
There are toggles you can turn on/off in settings that allow you to control which music app it searches.
