Sort songs by band, year, album, title in WinAmp

Go to Preferences > Titles > Use advanced  title formatting when possible and enter one of the following

• %artist% - %year% - %album% - %tracknumber% : %title%
• $if(%artist%, %artist% - %year% - %album% - %tracknumber% : %title%, $filepart(%filename%))

or in the comment I put the country of the band and used one of this

• %artist% [%comment%] %year% : %album% : %tracknumber% - %title%
• $if(%artist%, %artist% '['%comment%']' %year% : %album% : %tracknumber% - %title%, $filepart(%filename%))
• $if2((%artist% [%comment%] %year% : %album% : %tracknumber% - %title%), $filepart(%filename%))
