Scott Kveton · Portable Playlist and other POSH-ibilities Meetup: "Before the panel both Tom and I were chatting about how there is really only one big problem that both Pandora and MyStrands face: catalog resolution. This is a huge problem that consumes quite a bit of developer time in both of our camps. Unfortunately, every playlist format out there simply punts on this problem. They point at some “resource” that is the catalog entry. Now, from a portability standpoint that’s great and I can appreciate the why’s of why you’d do that."
the Wordpress of Lucas Gonze: "Or is the real problem still economic and not technical? Are there features which it would be profitable to support which entail portability? The problem isn’t how to enable portability, it’s why a business would want that. The status quo is lack of portability, with each music service an island. This sector as a whole hasn’t developed into a collective ecosystem, and businesses which do invest in portable identifiers don’t stand to gain any value until other businesses join them."
