While I clearly understand the desire to remix songs from days of yore, my personal feeling is that you get to choose to purchase them or not.
I like the original vinyl that I bought new back then and will always play it. If, for some reason, I happen to like the remixed versions, I will put my hard-earned money on the counter and make the purchase.
So far, I have only heard one "remix" song. It is from the Eagles, and I don't care for it. Unfortunately, I have to look hard on the internet to find the original version as I don't happen to have the vinyl. I will, however, purchase it if I find it. Oh, the song is one of my favs, and best, IMO, in the original mix: Please Come Home for Christmas. (The Bon Jovi version, while not as good, is by far the sexiest video I have ever seen, and they perform it with their clothes on!)
Cheers!
