I’ve noticed, from time to time, that tags on music files displayed in the iTunes Store don’t always match what’s in the files when I download them. There may be minor differences in the way tracks are named; but there has never been any major differences.
It is most obvious, however, for an album I bought today: Hilary Hahn’s In 27 Pieces: The Hilary Hahn Encores. This album, a group of pieces that Hahn commissioned to be played as encores, contains works by 27 different composers (actually, 28, because there’s a “bonus track” on the iTunes Store).
If you view the album on the iTunes Store, you’ll see the composers’ names:
But when you download the music, the Composer tag is empty:
I’ve seen minor differences in tags before, but never anything as blatant as this. I wonder why the iTunes Store has two different sets of tags.
Oh, and, if you like contemporary classical music, this album, In 27 Pieces: The Hilary Hahn Encores, is a real treat.
