Amazon has slashed the prices of many popular MP3 downloads to 29p in an effort to gain market share from iTunes. This move may spark a price war between the two companies. While Amazon's lower prices pose a threat to Apple's dominance, industry experts say Apple is unlikely to be dethroned soon due to its large customer base and the convenience of iTunes. The long-term challenge for digital music stores is finding new ways to attract traditional music buyers and generate revenue beyond individual song sales.
