Last.fm offers free web music - with a catch

Last.FM says hello to free music and goodbye to some of its revenues

Last.FM, one of the world's most popular music social networking sites, has undergone a series of business model overhauls in an attempt to turn a profit in an industry that's riddled with piracy concerns and an over-zealous music watchdog.

In an attempt to break away from its current model, the company announced on Wednesday that it would allow site visitors to stream any song they want for free. Citing an agreement signed with all the major record labels and 'thousands' of independent labels, Last.FM said it can legally allow access to any song in its library.
