How view and delete songs???

'maheagan bel slama' is the song.  I used to be on Pandora. I migrated my songs and playlists from Pandora to Deezer as per Deezer instructions. There is one song that I have never listened to. Never saved. Don't want to hear. And it keeps showing up in every single one of my playlists. And no matter how many times I delete it, it's still there. How do I view my music by songs as opposed to playlists? And how do I delete a song from my music like you can on Pandora?
