Thanks - really interesting idea. We can already make the exact duration and number of beats work, so it would be a question of lining that up with various points in the video.
You could ask for a naming convention in Premiere -- so that various clips or chapters are tagged with #dark or #exciting in their title, and then Jukedeck would play the appropriate type of music at the right time. If you can't get it lined up perfectly, you should transition the music before the video cut, not after.
The start time for a clip is much more important than the end time, so you should adjust the cutoff time for the clip by shrinking it from the end (never expanding it, as clips are often truncated when the footage becomes unusable, i.e. when someone walked in front of the camera, etc.)
I can imagine a Premiere plugin with a stored credit card, and you guys doing a brisk business that way. You could even then become a marketplace for royalty music, have a store where people can upload their music tagged with moods, and video creators could see royalty-free options from Jukedeck or royalty options from third parties.
Places you can add unique IP are: the ability to extract a mood from the video clip itself (most likely through color grading, the speed of pans, the frequency of cuts, and whether it's tripod or handheld), and the ability to automatically extract a mood from 3rd-party music, so I can automatically see the pop songs that are best fits for my video.
Find a way to do this without having to upload the actual video file, because that will kill the experience. Work-in-progress video files are often multi-gigabyte.
