"A new online music service called La la Media Inc. aims to offer full-length CDs for $1 by letting members trade used physical discs, in a new twist on the popular but legally challenged practice of online song swapping. Backed with $9 million in funding by Bain Capital and Ignition Partners, La la works like an online music co-op by enabling members to trade physical CDs they own for physical CDs they want, Bill Nguyen, co-founder of La la, said ahead of the Tuesday announcement. With 1.8 million album titles available, members trade the CDs in prepaid envelopes, much like popular mail-order DVD service Netflix Inc. operates."This is one of those cases where what they're doing it technically legal, but in my opinion wholly immoral. It's one thing to lend a CD to a friend, it's another to build a business around it. Disagree? Tell me why.
