Just like weather apps for iPhone, there is a ridiculous amount of music apps too. However most of them are complete crap and don't half work or look really ugly, they don't give you a different style to the stock music app which is more than capable. But T3 is a music app which is very different. The design is something you rarely ever see in other apps and is inspired by Dieter Rams. Parts of the app look like his own products that he designed decades back. It really is a beautiful app and is a great example of how to create something different. Though it may not be the best for user experience, it's still a lot of fun.
