I found another code for something very similar, but that code was not as clean and nice like this one! I think maybe using the reference mentioned also did it's part to keep this clean. However, what the other code had is that you navigate yourself to where you want to pick up files from. I think that is probably what people would prefer to do, then writing it down like this. On the other hand, some people might use it in one and the same place always. As for me, I am combining this code with code for creating playlist. I just need to figure out the filtering out of songs to the playlist. It's odd that no one really made a complete (free) simple solution for picking up like all songs we have on the drive, and then let you pick which ones to play or make playlist for :)
