Universal Music Group lost its lawsuit against an eBay vendor who sold promo CDs. I will link to a post by the EFF's Fred von Lohmann, one of the lawyers that represented the defendant. Here's an excerpt:

In an important victory for the first sale doctrine, a federal district court today ruled that selling "promo CDs" on eBay does not infringe copyright. The court threw out a lawsuit by Universal Music Group (UMG), which had argued that the "promotional use only" labels affixed to these CDs somehow conveyed eternal ownership on UMG, making it illegal to resell the CDs (or even throw them away). ...

In its ruling, the district court found that the initial recipients of "promo CDs" own them, notwithstanding "not for resale" labels. The court rejected the notion that these labels create a "license," concluding that the CDs are gifts. According to the opinion, "UMG gives the Promo CDs to music industry insiders, never to be returned. ... Nor does the licensing label require the recipient to provide UMG with any benefit to retain possession." (The court also found that federal postal laws relating to "unordered merchandise" establish that promo CDs are gifts to their recipients.)
