WMP gets the data the way most computer audio programs do, by comparing a "waveform" (a combination of track lengths in miliseconds, number of tracks track gaps and peak volume levels at certain time locations) with a database of similar data used to identify CD's.
Ever notice that sometimes two completely different CD's are proposed as a possiuble "match" to the CD in question?
That because although there are a near infinite number of possibilities occasionally two differen CD's will hav characteristics cloe enough that the database comparison software will question it.
Like a 3 doors down CD that resembles a classical music CD....
OR a Led Zeppelin CD that gets confused for a jazz album, etc...
Delete the cookies on a computer and start feeding it CD's and you'll get some amusing comparisons:)
Want your CD identified? take a copy of it to every computer you can find and load it into the drive... as the CD is entered into the database the first few times it'll say it's unable to identify it
and force you to enter the data manually.
After a period of time this will become unnecissary as you enter the data several times from several sources into the same database.
Hey, when I first inserted my new at the time AC/DC "Black Ice"
it was a "no hit" on three different databases.
So I entered it manually....
I'll bet that those databases would identify it now:)
Though CD-Text is far from universal more and more new CD's are having it, because the CD-makers are catching up to the reality that most aftermarket car stereos over the last 4-5 years have this capability, AND people have gotten spoiled by portable mp3 devices
and satellite radios that identify all songs by artist and title...
The record labels have adopted it as another piece of wreckage from their sinking ship to cling to to get a few more breaths before they drown.
Frankly I don't object to $12 Cd's, what I object to are $15 & $18 CD's
