More than five months after its faulty launch, legal peer-to-peer download site QTrax is finally making strides toward getting up and running after inking a deal with EMI Music. The deal allows users of the ad-supported music service to have unlimited streams and downloads of the EMI catalogue. EMI is the second major label to align with the service after Universal Music signed a contract with QTrax last month. QTrax was supposed to launch in January, but then they realized the deals they thought they had with the four major labels didn’t exist. Yesterday was a busy day for EMI, as the label also agreed on terms with Spiralfrog, another ad-supported music download site.
