Getting cover art for multiple singles in one folder


I have a folder with around 1000 singles (from various artists & albums).
The ARTIST & ALBUM tag fields of all the singles are empty, and basically the only tag info on the mp3 files is the title which is identical to the file name - set up as ARTIST - SONG_NAME.mp3

Now I would like to add cover art for every single file automatically. Is that possible?
