[Feature Request] Extend playlist - like how we get a song mix, but using multiple songs as the input.

This playlist extension mix takes into account all your songs in your playlist and fills in more songs that should probably be there.. It would be a great flex of deezers music algorithms! I believe this would be a game changer new feature and attract a lot of new customers. Thank you for reading and comment if you support this idea.. I believe it will change everything!!!
