Two questions while I am implementing this feature:
1. Would this be on a per post basis? For example, if you are writing a blog post on a great new song, would you need a meta box that asks you for a link to spotify? That way the individual song would appear with that blog post(or custom post type)?
2. Would this be better served as a different plugin? It seems to me that you don’t really want any of the other social features of WPsocialite, just the lazy loading feature for spotify, is that correct?
If number two is correct I may just wrap a new plugin all together. That helps you to make sure the plugin does only what you want, and it doesn’t bloat the WPSocialite codebase.
Appreciate your feedback!
