I bought the Karabits "album" (3rd Symphony and Grazhyna) on Apple's Itunes, but the files are corrupted - they have no sound content! Has anyone else had this issue?!
No, but I wouldn't touch Apple's Itunes with the bargepole I keep specially for not touching things with.
Oh, how come? Is the quality bad?
If I'm going to BUY something, I want as physical CD that I have for ever. Otherwise I'll use a subscription service.
Same here although recently I've taken to downloading symphonies not available on CD and then burning them so that I have a hard copy, as in the case of Shchedrin's great First Symphony conducted by Anosov.
