I did get my .mp3 files to play inside the music folder. I am happy that .mp4s work as well. I could have sworn that one of the read me files said that you could also place these inside a video folder so that they will play randomly like the .mp3s. If this isn't the case, hopefully that option will be included in a future build. I have to say that these new options (grid view, video view, basic view) have been implemented nicely. The presentation of the themes looks more vibrant too :-).
