This album had a long standing #1 single, but Shangri did sell more in it first week ..
They were different times back then. When Shangri came out, everyone didn't have an iPod, and music was a lot more physical back then, now it's 99% digital.
I recently looked at the top YouTube videos of all time, and most of the top 20 are music videos. Back in the Shangri days, videos were still relevant on TV, now it's all online. There's no reason NOT to release 'Cinnamon' since it'll just be for sale on iTunes, and available to watch on YouTube.
