I think a little different thing is meant here. For example, when you are in a bad mood, you can turn on upbeat, energetic music, and this way you can feel better. Or if you feel like being sad, you choose sad songs to fully experience your emotions. By the way, I prefer to listen to all the music on my phone, downloading it using the online service Tubidy. I can definitely recommend this service because it's free, but all the music you can find and download is in excellent quality. It can be a great alternative to such popular music platforms as Apple Music or Spotify.
