This increases the vertical scrolling speed of Music player by around 50%. You can scroll 300 songs in 10 seconds using this. This is the maximum possible speed that can be achieved without directly hacking vshmain.prx.

It works in the Photos menu as well if you open the Music player first.

Install it under SEPLUGINS in VSH.TXT
