When you ask Siri to play a song on iOS 14.5, you may be prompted to select which app you want to use to play it, according to a screenshot shared on Reddit.

I’m on the iOS 14.5 beta, but interestingly, the feature worked a bit differently for me. I asked Siri to play some Tame Impala, and I wasn’t presented with a list of apps to choose from, like in the screenshot above. Instead, I was shown a prompt asking for access to my Spotify data, which I allowed. After that, requests for songs went through Spotify without any prompts.
