^Decent list but half of it is from the 80's.
Apparently, looks like 22 records listed here are actually from the 90's and only 5 are from the 80's.
There's a huge possibility I might be wrong since I don't own the original records, have em all on tapes and had to look it up on the net for the original release dates, again. My apologies.
Then, if I'm not mistaken, well...there's a huge possibility you never finished elementary school, 'cuz your math sucks dude
