Hi Deezer,
I think it would be a great feature to create smart playlists based on user defined criteria
Interface only needs to be a list of dropdown menus and text entries:
example template
Text: Playlist name
dropdown: Artist/Album/Rating/# of listen/date added/ etc…..
comparator dropdown: is/=/!=/>/</is not/contains
Text: user value
add criterion buttons: AND/OR
example
artist = XXX
OR
artist = YYY
OR
album contains ZZZ
source of data could be either all of deezer or just any song in favorite <union> downloads <union> album <union> artist
