Why are songs in my playlists replaced

I use deezer with just a few playlist in wich i put all my music in, synchronize them to my phone and listen to it all on random.

Today as i listen to my music is start to hear the beat for the song “Donald Trump” by Mac Miller but its not Mac Miller its some wierd version by Bobby Gutta called Loose Leaf. I never heard oh this artist, never put him in my playlist.

I search my playlist to make sure the Mac Miller version is still there, can’t find it. So i have to remove the shitty version from my playlist re-add the Mac Miller one.

wtf is happening ?
