My jukebox software relies on the following directory structure:
\MainDir\Artist\Album\SongFile
Reading ID3 tags to determine stuff like Artist, Album, etc... would not be beneficial in my jukebox software since it is "directory structure" related. I do not build a hugh database of all songs and album covers at load time. Basically, my software would not know what to do when reading ID3 tag information at all. As a result, I do not plan on supporting it. I also have heard that ID3 tag information can take too much time to read in and that some people do not like to rely on ID3 tag information since a lot of the information is incorrect. I have never heard (until now) of someone putting lyrics into the ID3 tags. Anyway, I am sorry, but my software was not designed with ID3 tags in mind.
You might want to try out the software first to see if you even like it. Test it out with about 20 files only and see what it can do. You might not care for it, or wish it behaved differently, then you would not care if it had ID3 tag support or not. Anyway, if you do decide you like it as is, then you could store all of your mp3 and lyrics appropriately in about one weekend worth of effort (since you said you have a 1000 files).
