Yes! The most sensical way to have album art for media that is not separated into albums by the file system (ie one folder for everything) is to include it in the id3 tag of your mp3.Originally Posted by Chuck
You are going to want to use the 'APIC' frame of an id3v2 tag (if you are a programmer that might make sense to you)
Alternatively there are many good programs out there that allow you to edit id3v2 tags (including album art) and even go so far as to try and download the art for you.
I recommend "Tag and Rename" and "The Godfather aka TGF" which can be easily found using google, etc.
