Someone uploaded tracks to my profile

I just noticed that there are three new tracks uploaded on my profile. I can't delete them and there is a note saying:
"This track is managed directly by its rightsholder, so not all options can be changed. To make other changes, contact your label or distributor."
I understand some artists signed contracts and allowed labels to manage their accounts. But this is not even the case... all three tracks uploaded to my page are not mine. I did not create them, never heard them before and they are in completely different genre than all my music.







How can i delete those unwanted tracks?
