Just a note on how you can peruse and access settings for older versions of muso, should you ever lose them:
If you browse the folders below for user.config files:
. C:\Users\<your username>\AppData\Local\Muso\<*.exe.*>\<n.n.n.n>\user.config
. C:\Users\<your username>\AppData\Local\AlbumBrowser\<*.exe.*>\<n.n.n.n>\user.config
These are the settings files for your previous versions (n.n.n.n).
