If you use Pandora, Spotify, or iTunes Radio to stream radio music on your iOS device(s), and you often take advantage of the thumbs-up or thumbs-down features to rate music, then a new free jailbreak tweak called OneThumb
by iOS developer rob311 is now available in Cydia and may be of use to you.
OneThumb integrates with Activator so that you can easily thumbs-up or thumbs-down music while it's playing in any of the aforementioned radio streaming applications. One Activator action is set to thumbs-up, and another Activator action is set to thumbs-down.
The tweak adds a preferences pane to the Settings application where you can configure the tweak and its Activator actions to your liking:
The "disable alerts" option will prevent notifications that tell you when you try to use the tweak with an unsupported application or when no media is playing.
Once we configure the Activator action that we want, no matter what application we're in when music is playing on a radio station in our favorite supported radio streaming application, when we invoke our thumbs-up Activator action, that song will be thumbed-up. Same for the thumbs-down Activator action, except with the result of thumbing-down the song.
Since the tweak relies on Pandora, Spotify, or iTunes Radio, you must use one of those three services to take advantage of this tweak. If you would like to give OneThumb a try, it's available for free in Cydia's BigBoss repository right now. iOS 7 is required.
iOS 7.0-7.1.2, Pandora OR Spotify OR iTunes Radio
iPhone 5 running iOS 7.1.2 with Spotify
