I might add an option of skipping scanning to future versions. Imagine this:

You click on ukmp.
Black /white screen open.
Then a question:
Would you like to:
Scan the system for music Use old library?
User clicks on scan, it'll scan the system and update your library. Click on use old, it'll just load the covers and be done with it.

Sounds like a good plan to you?

Out of curiosity, how long does it take you to get to cover screen in ukmp?
Out of that, how long does it take for it to move from the scanning text to the mode where it is showing one cover at a time at the bottom of the screen?

Because scanning is the first part and the part where it's showing one icon at a time, is the part where it's creating the mirror effects to the covers (and stuff like that, which takes time).

Also, I would like to know how big your music library is.
