In these globally conscious times - where wasting precious resources on trivial things would be a shooting offense, if we could only spare the bullets - everyone loves a good recycler. Music is no different, in this regard. You can recycle old sounds, or old guitars, old ideas, old clothes or old poses. You can re-use the swagger of an olden-days singer or the hairstyle of some rock grandad or other. It's all there for the taking.
The trick is to find something which hasn't been recycled so often it loses its original shape and starts to get a bit baggy at the seams, so you end up having to basically remake the whole thing from scratch (Glee people, I am looking at you).
Credit to wiley old Mr Wiley then, for finding a sample of a late '90s hit which itself contains a sample of an old song from the past. This is therefore double recycling. He can basically drive a Hummer into a panda now, and he'll still be ahead of most of us. .
