"MSN Music (music.msn.com) is by far the most capable rival to Apple's iTunes Music Store, even if it doesn't yet surpass it," says The Washington Post.
"Shopping the store is a pleasure, whether in Microsoft's Windows XP-only Windows Media Player 10 or through a Web interface (you can only buy using the Windows version of Internet Explorer). Type what you want into a search form and results are cleanly presented a moment later; each track shown comes with a 30-second sample and a rating, from one to five stars, based on other users' input. This search engine will offer to correct typos, even the most obscure -- it fixed my attempt to spell Einsturzende Neubauten."
