Ah meen vaag te herinneren dat het doen ineens op spotify stond.
Edit: Wikipedia helpt:
To Pimp a Butterfly was first released to the iTunes Store and Spotify on March 15, 2015, eight days ahead of its scheduled release date.[59] According to Anthony Tiffith, CEO of Top Dawg Entertainment, the album's early release was unintentional, apparently caused by an error on the part of Interscope Records.[60] The following day, it was made unavailable on iTunes, and the release was rescheduled for March 23, although it was still available for streaming on Spotify.[61]
