I agree with you all with what you are saying but if you are writing a new track, is it ok to call it a remix? It feels to me that, as mentioned before, this is totally a marketing gimmick. If it is completely different why are we calling it a remix? I think a remix should be a different interpretation of the original, like the expansion of the original.
If you don't like the original why are you remixing it in the first place? Either for money or you feel like some changes/additions would correct/improve the original. If you can take something that is average and then create a masterpiece out of it then you are the true remixer.
Hearing overplayed tracks is a different subject imo. If I am tired of hearing the same record, I wouldn't buy/play simillar sounding shit in the first place. So when I'm looking for a remix, It's either I know/like the original track or the remixer(producer) and have an expectation about what the remix would sound like. When you get a completely different track, it is a dissapointment as far as the remix business goes, although as you have mentioned before most of the times so called "remix" is much better than the original. And if all the remixes on a release sound the same, well then that's the label's fault.
well, yeah...
