This will be appearing sometime in 2015. When Yosemite was revealed it was clear we'd have to change the style of the app to fit in with the new UI. But it also gave us an opportunity to rebuild things, make the app smoother and add features people had been asking for. I'm using an early build from Alex (the developer) and it's incredibly fast, thanks to a rewrite in Apple's new Swift language and a bit of rethinking.
The first thing you'll notice is the lack of track art. In the current app this is never consistent as it's loaded in from the top search engine result, so it's not useful in helping identify tracks over time. In place of that in the Popular section, a mini-graph shows momentum in a track's popularity; whether it's on the up or down, and how fast it's getting there. Other sections will use that left area to show the number of likes.
We're experimenting with a few new sections too. We want users to be able to see Blogs, Genres and Friends for them to explore Hype Machine and not be restricted to popularity. We also want users to be able to click on any track or artist and explore the remixes or other songs, just like on Hype. You can see some additional teasers on Dribbble, such as a new way of seeing track info, the Blogs view and a new app icon (the lightning bolt is dead!).
It's brilliant to see people including Plug in their daily routine. We'll work to get this over to you next year, and we appreciate the support, suggestions and patience.
