A friend sent me a cdr of a recording he'd downloaded (I think from e-music). It was a compilation called Be-bop Revisited. The only information he included was the name of the band leader or group on each cut (eg Oscar Pettiford, Al Haig.) Recently I was using a rented car and stuck this cd into the car's player. I glanced down and noticed-- much to my surprise- the the cd/radio's read out was showing the title of each cut. Then I almost drove off the road when it gave not only the name of the group but added the names of band members! Usually about 4 then just saying "plus others". (Eg Oscar Pettiford and his 18 All Stars with Dizzy Gillespie, Trummy Young, Don Byas, Shelly Mann and others".
I got very excited (I'm easily excited) at the prospect of finding this kind of discographical information on other cds, but much to my chagrin even though I tried regular cds, cdrs and downloads I never found another one on which the player was able to find any information except the track number. And I never found another player that displayed such information from this cdr. I've since returned the car so can't experiment any more.
So my question is: What the hell is going on here?
