An anonymous reader writes "Google has sent out press invitations to an event on Wednesday where it's expected they'll unveil their long-rumored Google Music download service. CNET reports that while Google already has an agreement in place with Universal, talks with Sony and Warner Music Group are still in progress, and won't be finished by the time Google Music launches. 'The negotiations between Google and the labels by and large have not gone well for either side. The labels are eager for a serious iTunes competitor to emerge and believe Google has the technological know-how, money, and Internet presence to give iTunes a run for its money. ... Yet, the company is once again launching a major part of its music service without acquiring licenses and this may serve to widen the rift between the company and some of the labels. '"
