I am a very poor programmer, and so far I haven't been able to find any expression that matches my exact need. I would really appreciate it if someone wrote down an expression by which I can filter my tracks using the cover art's dimensions. A while ago I lost all my good quality covers, and they got replaced by covers, all with the dimensions 320x320. Therefore, I want to filter it so that I know which covers to replace.
Any help is highly appreciated!
