You're not the only one who feels that way, and you have every right to express yourself

Now, here's my 10 cents:
The real thing is old, remixing it again now (even once) is not letting it die

After that, who cares if it's just once or if it's ten times?
Personally I wouldn't mind if it was remixed, as that's no different than me still enjoying the old version, or the remixes that were done at the time.
Why should I be allowed to still enjoy the old version, but be opposed to allowing someone else who enjoys it trying to revitalize it?
You could argue that it won't sell, or that DJs stuck in the past won't be successful because they aren't keeping up with what's hot right now, but you just can't stop people from expressing themselves or liking what they like, even if it doesn't fit with the popular trend.
I don't think music has an expiration date, and I think it's funny when we try and take something as abstract as art, and force it to fit into some sort of box, or rules structure.
It's like we are trying to lasso it with cold hard logic, and we can't figure out why we can't contain it!
