Add your own songs to a playlist

[Liccao]

Ey my dear community.

On spotify there is a song I realy like but because I live in Denmark it is unreachebel  that means I have to buy it. That I have done but my question is can I somehow upload it for my profile so when i add it to my playlist I can hear it like all other songs trough my playlist.

This also means that I need to be able to hear it on my phone too without have the song laying on my phone also.

Hope you can help me
