Mediabrowser questions

Hello,

HA uses the build in /media location to play music files.
My questions are as followed:

1 - Is it possible to put different folders inside that location? This is done to organize songs by artist, instead of one huge list of songs. I tried to put in a map with songs and it did get recognized, only when i try to play it it gives me a error saying invalid path.

2 - Is there a way to play ALL songs inside a map instead of just one? And have some control input as shuffle/skip etc?

Thank you
