I do not care for remixes at all. I do not care for singles either.
But well I do think that singles like this filled with remixes like this do indeed serve the dance-scene, the remixers and the record company some good. They might attract some other buyers and make the record company some money.
And that might sound sort of bad at first, but well the record company has to make money somehow and I prefer them putting out a hundred crappy dance remixes just for commercial purposes over them trying to push the albums to be more commercial anyday.
