I would have to say that the music was digitized at 48 Khz. This is the default sample rate in the professional world. A cd will only play at 44.1 Khz. This would explain your pitch shift. If you are old enough to remember lps, it would be like playing a 45 at 33.
Check your digitizing software and make sure its sample rate is set to 44.1 Khz.
