It seems Amazon and Walmart weren’t immune to pressure from the music industry. Just one day after Apple eliminated DRM and introduced variable pricing
to iTunes, the two major online music retailers are quietly making the same shift
. Amazon MP3 now has prices ranging from a low of $0.69 to a high of $1.29, the same as iTunes, while Walmart is still marginally cheaper going from a low of $0.64 to a high of $1.24.
Hit songs in general will cost more, while music from an emerging artist might be priced at the lower end of the scale to encourage purchases. However, prices for a particular song can vary from site to site, requiring music shoppers looking for the cheapest price to compare across stores.
