Picard and "EasyTag" - 3000% motherfucking piece of shit!!!
Puddletag rules motherfucka!
From Russia witn love.

There are a lot of audio tag editors available both on Windows and Linux. This is likely due to the fact that everyone seems to have slightly different preferences on what to tag in their files. Puddletag is very similar in style to the Windows software mp3tag (mp3tag.de). Tagging is very flexible and should cover everything you need (album artist, cover art, etc..) and the developer is open to new ideas.
