Slow down or speed up playback (without changing the pitch)

In the latest version of SmartPlaylist (v6.3) you can change the speed of the music playback. You can slow down to 0.5x or 0.8x or speed up to 1.2x, 1.5x or even 2x. The pitch of the song is not changed by this.
This can be easily and quickly done in the playback control of SmartPlaylist, which can be accessed from anywhere, at any time with "♬":

You can use this new feature

• just for fun
• to scan for a specific playback position
• for quickly going through MP3-lectures at 1.5x or 2x playback speed
• to play along at a slower speed for practice

Limitations:

• This only works with iOS 6 (not iOS 5)
• On the iPhone / iPod the control is only available in portrait mode, but not in landscape mode (there is not enough space in the pop-up). On the iPad it is available in both modes.
