Adding all file from a folder to current playlist

I have my mp3 files sorted in folders. One for each artist and i was wondering if it is possible to add all files from a folder to be added to the current playlist? It's rather annoying to create playlists for each artist so that i dont have to add 100+ files to my playlist every time.

But either way on the left menu you will see the folder name (shared folder name. Double click it and then all music folders will display to the right side and press the green + simbol to add all the folders contents.
