This has the originals of several hits that you can't find anywhere else.  Of course it's from the 90's so the mastering reflects that, and who knows the origin of the source material?  Regardless, I'd been seeking original recordings of the group's classic releases for some time, so I was pleased to run across this.  Most of the collections currently available (newer releases) are re-records, so it's buyer beware.  They are "okay," but they're not the originals that we listened to on the radio back then.  I believe this is out of print, so most likely you're going to have to find it used, which is what I did via Amazon.  I can verify, as best I can tell, that these are the original recordings.  Do not know if they were album or 45 single cuts, but they're good enough for me.
