They have a very comprehensive database of Latin American artists that includes bios, pictures, discographies, lyrics, etc. They have been very useful in filling information gaps that are hard to find and many of the artists that they have, I have yet to find elsewhere

This is however a for profit database (much like allmusic.com). You can find more background about it here:
