Kaleea, the pitch on most of the old 45's that I had was generally pretty good, as long as you used a turntable with a strobe so you could keep the turntable speed precise--The same recordings, now remastered and released on CD, and, it turns out, even a lot of old 78 recordings, now on CD, are pretty true to pitch.

One of the problems I have with new "pop" recordings is that they don't sound real--pitch is evened out digitally, harmonies are added with a harmonizer, and their is none of that edge that the natural variations in pitch used to create.   Even all that shmaltzy music that I used to loathe sounds great compared to the stuff passes for popular music these days--
