A new US music download service is offering CD-quality music downloads.

Business Week speculates that this could be a signal of the future of digital music services, as it offers end users the same quality of sound as they enjoy at retail. Existing services only offer compressed audio formats, and many audiophiles complain this means lower quality sounds.

"If the digital music revolution is to reach its full potential - an all-digital future, perhaps, in which CDs racks are no longer needed - analysts say the industry will have to hit a far better-sounding note," writes Business Week.

The new service is called MusicGiants, and demands a n annual $50 membership charge (which is waived for members downloading $250 or more of songs) and songs cost $1.29.
