Do you live in the now or keep a foot back in the past? Better yet, what should an API provider do?

If you are looking for sound samples on the web and want to add them programmatically to your apps, the Freesound API may be just what you need. Freesound is a collaborative database of Creative Commons Licensed sounds. Users can join Freesound and upload their sound files and share it with others. Recently it also announced that it has crossed 100,000 songs in its database.
