what is the first song you will turn on when you're using your laptop?

When I turn on my laptop and start serving the internet , the first song that I will listen to is Focus by Ariana Grande.
And then I will click "50+ Videos Mix Youtube" Something like that... to listen to all the song on Youtube that are in the social tread now.
Actually , My first song can be changed. It is up to my favorite artists as well.
Maybe when they come out  their new song. Then my first song will be changed , if I like the new song most.
I think everyone has your favorite song or the first song that you will always turn on before going to do other thing.
So, I want to know what the song is. Maybe It will let me know and understand you better from that song.
