I just finished some major changes to our MP3 search engine, MP3Lizard.com. Most important change is HTTP result set -- finally we got this very important area back. With FTP results, you may get more results (and you will), but results are very unstable and hard to download. With HTTP, results are very reliable -- only weird thing might be the filenames, but you get used to it :-)
Also some layout changes for results, etc.. Check it out, MP3Lizard.com!
