I've come to appreciate the new Your Music section as an aggregate for all of my listenings on Spotify and would love to see it expanded to allow local files.
This would bring the Your Music function of Spotify into the realm of a complete musical collection (which I believe it aims to be),
similar to the Library function of the 0.x.x. version of Spotify, but with more choice involved.
I believe this wouldn't be too difficult to implement.
Thanks for listening.
