MP3's and Internet Lookup [CDDB?]

Factual Questions
1
      • This was in GQ some time back: somebody asked how MP3 software can identify the CD in your cmputer by only by the track length listings. Is there more than one CD database? (mine consults something named CDDB) I ask because people commented that only very rare CD’s didn’t return with results. I bought a Diamond 500 yesterday, and I noted that U2’s Mysterious Ways pulls a blank(!). - MC

Regular CD software can use CDDB too, not just MP3 players. I don’t know if there are any other free databases, but there’s a CDDB faq you can read up on here:
