Ask HN: Whould you use API for licensed music/movies DB?

Hi guys, Most of you heard that building music startup is very hard. Anyone would be interested to challenge that? What if you could use API similar to twilio/paypal/aws etc to access db of licensed music and movies? Would anyone be interested in building their own Spotify/Guitar Hero/Pandora/Last.fm/Netflix/iTunes having such thing? Please explain why. We are currently evaluating adding API for our service. Thanks!
