I've been playing with LaLa.com for a little over a month now. So far, I'm really loving it. LaLa is a service that allows you to trade music, legally. Rather than venturing into the virtual red light district of the internet to get poor quality MP3 files, you trade phyiscal CDs. Just list all the CDs you have that you are willing to trade and then list all the CDs you want and LaLa makes it happen. They even supply the shipping kits. Once LaLa finds someone who wants one of your CDs they'll let you know. Using one of their special mailers (that look a lot like what Netflix uses) you drop your old copy of Rick Springfield's greatest hits in the mail. At the same time somewhere else, someone is dropping their copy of Seu Jorge's David Bowie covers in the mail to you! LaLa requires that all the CDs are the originals, so you cannot send a copy of a burnt CD, or someone burnt from downloaded music. The good news is that since you are trading with a network of 'friends' then its probably legal for you to make a copy of a CD for yourself before sending the orignal out the door- and that clearly appears to be the way most users are using LaLa. 

 For about $1.00 per CD that you receive, LaLa is a great way to test the waters on new artists or replenish all those stolen CDs from college. The downside comes when you are waiting patiently for someone to send something popular while all you are getting is the older more dated stuff on your list. Like Netflix, LaLa seems to rely on a karma system. I've noticed that the more I trade, the better the stuff I get. I also noticed that I kind of had to put myself out there at first. I sent away five discs before I got any back. However, once things got rolling then the trading was pretty much 1:1. So far, I'm sold. If I need something I don't feel like waiting for, I can still go buy it. Then I just move it from my "want" list to my "have" list. You can also re-trade CDs you receive from other members. Frankly, for $1.00 its not a lot to risk to try LaLa

 By the way, you can keep tabs on my "want" and "have" lists at the bottom of this page...
