MP3 files still in Computer after using delete files and emptying the trash

Hello,

I recently updated my music library to higher bit rates and deleted the lower bit rates in my iTunes library by using the "move to trash" option and I went to empty the trash bin for permanent deletion and executed by emptying the trash.

Thinking that the lower bit rate music was deleted, I had checked one song and clicked it in the "Finder" so it would play in the library.... that song I deleted was still there along with the newer song I recently put in.

All the songs that I have deleted and trashed are still in the "Finder" months later, so is there a simple way of finding the lower bit rate 128 and 160 etc music that was deleted and trashed without entering the music back to the library and just finding the files in question in the "Finder" this will really help me, Thank you
