Spotify lets you use Siri commands to play and control music on your iPhone, but it wasn't always like that. It only applies in iOS 13 and later, so if you're on an older iPhone model with an older iOS version, you can use a really complicated workaround in iOS 12 or try a jailbreak tweak on older firmware.
With the AssistantLove tweak, from the development team at Delta, you can add at least some third-party integration by allowing Siri to play music from Spotify on older iOS versions. Our guide below showcases it on iOS 8 but it may work on other iOS versions too, though, it may not work on iOS 11 or 12. We've only tested it out on iOS 8, so we can't say for sure. But it definitely also works in iOS 5 and 6.
Just make sure you have a jailbroken iPhone before continuing.
AssistantLove, which was called AssitantLove 2 Beta when we used it, was not available through any existing Cydia repository since it wasn't fully ready for primetime. However, if you're on iOS 5 or 6, you can use AssitantLove in the BigBoss repo instead of the Delta repo. It might also work on other iOS versions.
For the 2 Beta version, go to the Cydia app, find "Sources," tap "Edit," then "Add." In the text box that appears, type in "getdelta.co," then tap on "Add Source." After a few seconds, a new source will appear called "Delta"—this is where the tweak is located.
Now "Install" AssistantLove 2 Beta, then tap on "Restart SpringBoard" so that your phone reboots and the tweak takes effect.
Now bring up Siri and issue a command to play a song from a particular artist. Once Siri recognizes the song (which was incredibly accurate for me), it will open up Spotify and play the song. Note: Make sure you don't ask Siri to play a song you already have saved on your device, or else she'll play that version and not the one on Spotify.
If you have a paid GrooveShark account, you can also pull music from there if you don't have Spotify.
Overall, the tweak didn't work 100% of the time, recognizing the song but not always playing it. Since I used a beta, it isn't all that surprising.
