CBS is adding on-demand, full-track streaming to its music social-networking site Last.fm. Free on-demands streams will be limited to three times per track, and cannot be downloaded to a portable player (e.g., an iPod).
Forbes notes that this is a "sign of the recording industry's growing interest in free, advertising-supported access to music". Yet, Last.fm plans to ultimately offer users a chance to purchase a monthly subscription allowing them to listen to songs as many times as they want.
Rolling Stone notes that the Last.fm deal with major record labels is heating up "the arms race" between Amazon and Apple iTunes.
