"maybe i don't know much, but i have this collection and i love it. i'm no expert on sound quality, but it sounds good to me. also, it has 24 tracks and they're all great (it's all early stuff)! it says it has "copy control" technology, but i'm not really sure what that means. it's always played and performed well for me. i like this cd better than abkco's "the best of the animals" cd."
