Why mess with a good thing?
Being the 80s child that I am, I absolutely adore Micheal Jackson's Thriller album. I have (still!) the cassette and I played the heck out of it back in the day. It turns 25 this year (dating myself here, I know)
They are releasing a 25th anniversary edition, but they have "remixed" 5 of the songs. If you get the chance, go to youtube and listen to some of them.
The songs are charming and timeless enough and are way better than some of the crap that passes as music these days. Why mess with it??
Once you've listened to the crappy new versions, find the originals and listen to them. So.much.better.
Thriller, by the way, is in my top albums of all time list.
