Aria is a jailbreak tweak for iOS that makes the stock iOS 7 Music app what it should have been. Not only can you tweak and customize views, Aria also adds the ability to queue music just like you can in iTunes!
A lot of people didn't like the stock Music app in iOS 7, which looks to be largely influences by the iPad Music app. Luckily, if you're jailbroken, Aria can help you tweak the Music app to your liking again. Design wise you can change the grid views, change some of the interface colors, and more.
More importantly, Aria adds some functionality that makes the Music app better than ever. For starters you can queue music by holding down on any song and choosing to play it now or queue it for next. As you do this, the songs just line up. You can also choose to shuffle music once albums or a playlist is finished. That way you don't have awkward gaps of silence where you need to go back into the Music app in order to turn something back on.
