Question: Starbucks Entertainment announced in a 2007 news release that Dave Matthews Band's Live Trax CD was available only at the company's coffee shops in the United States and Canada. The compilation features recordings of the band's performances dating back to 1995. Why would Starbucks and Dave Matthews have agreed to partner in this way? To come up with an answer, think about the nature of complementary goods and how both sides can benefit from this arrangement.
