WidgeTunes is a Notification Center widget app that lets you choose to play your favorite music or playlist without unlocking your phone or open the Music app of your iPhone.
This is really handy for me as most of the time I stick with playing the Top Rated playlist, or sometimes, a specific album. And this is something that the Control Center music section cannot do.
Similar feature is used to be jailbreak-exclusive but no longer the case now as Apple opens up the NC Widgets to the developers, sort of.
Anyway, you can download WidgeTune now from the App Store and save $0.99 instantly.
