HTML5 MIDI JAVASCRIPT SPIKE code #3 - Pick multiple MIDI song files from the app-supplied MIDI song folders and play them.

This is a user story spike - not a finished project - it will leverage existing proprietary files. The winning bid developer must sign an NDA and IP agreement s (handled through Freelancer) prior to being awarded the gig and prior to starting the work. Here is the user story spike that needs to be completed to receive payment. AS A user of a MIDI Playlist Player app I NEED to pick one or many midi files from an app-supplied MIDI song folders and play them SO THAT I can select and hear MIDI songs on my device that I don't have in my device folders Acceptance Criteria. There will be a new "Select Demo Songs" button to the left and on the same row as the "Choose Files" button, which will allow the user to select song files from the App-supplied folders (instead of the user's device's folders). For example, one folder on the server in the subfolder in the JavaScript and other app files, might say "Early19thCenturyPianoSongs". Another might say "Rock", "Folk, "Blues", "Jazz", etc. Like the input file command in HTML that allows a user to traverse folders and select .mid songs from the folders to be put in the playlist, this new feature uses the App's server folder as the location of the main MIDI files folder partent of the many subfolders of App-supplied public domain or licensed MIDI files. Selecting them and adding them to the session's existing list (which includes prior ones chosen from the personal device) and keeping the MIDI Playlist Player functioning is required. If you have any questions or comments, please let me know. Thank you. James "Jim" - Mr. Surfview
