Virtual music organising cupboard

Dear Deezer,
I would highly appreciate an extra way of organising my music in the Deezer app. I was thinking about an extra category aside from playlists, albums, artist, etc. that functions as a virtual cupboard with multiple slots in which you can organise in any way you want. Name it yourself and be able to put in and combine existing playlists, albums, individual songs, etc. Right now I have about 30 playlists and over 200 store albums, but they start to become difficult to navigate through. An extra way to organise and sort all this music would be highly appreciated.

Kind regards,
EVLV
