LaLa is a cool music website that lets you play, buy and share music on the web.
What do I like most about the site? It lets you listen to an entire song and then you can decide to purchase it. After you listen to a song the first time, you can always play a 30-second sample.
For those passionate about music, there's many more features that I haven't explored yet.
Apple acquired LaLa in December so your music may be coming to a cloud near you.
