Super Song - Lousy quality

I seriously wonder if there is somewhere a quality check for MP3's from Amazon, because these mp3 is worth your 99 cents in any way. No highs, no lows, much too quiet and a listening experience as you put his head in a bucket of porridge.
The song itself would be 5 star, at the lousy quality, but you should think twice if you do not yet better buys than the single CD .....
