I point it out as a matter of education, and yes I usually send a PM to the person just to let them know that they should go in and change it. I try not to be rude or nasty about it, and I hope my posts do not come across that way. I'm passionate about teh subject but never mean. (I have been colecting original cast and soundtrack recordings for over 35 years now!)
I stand by my earlier point: let's lose the term soundtrack (for at least the purpose of Broadway World) and just use either the generic term CD or the perfectly correct "cast recording" or CR for all show recordings, film and stage.
This is not such a radical idea: because of sound quality issues, very few movie soundtracks are actually recorded directly from the film soundtracks any more. If you listen to older discs of actual soundtrack recordings...THE MUSIC MAN on Warner Bros for example or some of the old M-g-M soundtrack albums, they all have a flat "boxy" sound quality.
They films are recorded that way on purpose, oterwise the sound would be too hollow in the large movie theatres. On records, however, they sound dull and flat.
In the 1960s some labels like Columbia (for WEST SIDE STORY, MY FAIR LADY, FUNNY GIRL and 1776) just added a lot of reverb to the records.
Capitol Records got around this by having the movie casts of OKLAHOMA!, CAROUSEL and KING AND I re-record the scores in studio for release on records. (They eve put the phrase "from the soundtrack of the motion picture" on the Lp covers, even though the Lps were not!) You wil notice if you listen to the original soundtrack albums for these films that the Overtures and some of the songs are completely different performances. The recent "expanded" edition on Angel incorporates additional material taken from the actual film soundtrack.
Today they can digitally alter and remix the sound for theatrical and home video use, and again for CD release. That is why soundtracks often do not sound like the performances you hear on your DVD of the movie.
That's a very long-winded technical explanation for you.
For those of you who think it doesn't matter, if that really is the case, please indulge the rest of us and just call them Cast Recordings.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
