Fast Scroll Music increases the vertical scrolling speed of the XMB by around 50%.

Changes:

Now only activates when the music player is open. When you open another part of the XMB, it will deactivate and the M33 VSHMenu will be restored. VSHMenu will not work while in the music player. Changed name to “Fast Scroll Music”.
