Am I crazy or my wish got deleted? (I guess providing a competing product as an example was not a great idea)

I organize my music by folders/genre/artist/albums/*.mp3, *.flac, etc...

I couldn't find a way to play an actual folder. The only thing available is to browse it (browse down one level)

I'm hoping to have a button to play a folder... The action would be to do a recursive search from that folder and allow you to play all files included in the tree.
(play order features: chronological, alphabetical, shuffled, once, looped, etc...)

Foobar2000 is all I use on my PCs since ages.
Dragging a folder in the interface creates a play list with all the files included in the tree. Please add something similar in the mobile version.
