New York - Users have reported experiencing problems with Qtrax, the free, legal peer-to-peer music download service that launched with licenses from the major labels this week, according to reports. Hypebot reported that searches for songs from many artists on major labels EMI and Universal Music returned notices that read "Coming Soon," while Wired.com said that tracks downloaded from the service initially would not play at all, but "are now playing just fine." A company representative told Wired.com, in reference to the gaps in its catalog, that "music is being added each and every day over the next few weeks in large batches."
