update: I tried with all my songs and yes I know it doesn't work with every song. I just think it works if you play the song on time or it works with some sort of upbeat song. But yea, it doesn't work perfectly like you would expect.
<<< adjust the non-emergency emergency services number depending on your country. It probably won't work in all countries. In England we can use 111 for those things, and the police have their own phone number, find your local station's
