Have a look at New Album Releases, you will find new albums as soon as they are released.
You don't have to install any software to download the files that are hosted on servers of different services.
They even have a RSS feed, so you can be sure you won't miss any new album.
I can't figure out how they offer such a service without being shut down by the RIAA in a couple of days, but it seems that they found quibble and they are actually DCMA compliant providing just links and not hosting anything.
Thanks to Pensieri Cannibali for the links that introduced me to this site.
