Yahoo! now let you play music directly from the search results page as part of partnership with Rhapsody. They’ve launched a music artist shortcut to make it easier for users to find quick details about artists -- like videos, photos, sample song tracks, and even their official website links.
Now, in addition to gaining access to all of the artist background that you could before, you'll also be able to play up to 25 full songs a month, as opposed to the 30-second samples from before. You'll also be able to link directly to Yahoo! Music right from the shortcuts; full song playback will soon be enabled in Yahoo! Music as well, so stay tuned.
To listen music, just search your song of choice and the new media player from Yahoo! Music, called FoxyPlayer, will launch near the bottom of the page. The player is easy-to-use and offers full functionality for song playback, like artist and song info and even an expandable playlist tab. You'll be able to continue browsing the results page while the player is in use or turn it off at any time with a single click.
