dont know how to use foobars compression options. dont understand. no guide!.......

Install
Foobar2k special version.
Go to Preferences -> Diskwriter. Select Output Format: Musepack and Ourput Directory. Then select quality under "Musepack Encoder".
Load the files you want to encode. Right Click-> Convert -> Run Conversion.
Then load the converted files and Right Click -> FreeDB -> Get Tags. This will tag your files perfectly. Then select files-> Right click-> Replaygain. This will replaygain them.
To make foobar look good check:
Foobar formatting and
Foobar looks. Unfortunately those plugins do not come in the special package but these sites clearly explain what you should do and it's easy.
