This site has Links to all sorts of christian artists, it lists all the different genres of christian music, pretty easy to find your way around the site.
There are reviews of the cds, concerts, etc. a list of genres where you can find the name of bands under a certain genre, and then read the bios of the artist. There is an interactive map of the US with all 50 states where when you click a state a page will list all (at least I think all) of the christian radio stations in that state, If you live in DC click the Star that looks like a compass next to Delaware. There is also Q&A, lyrics, and even comments.
There are pictures of different bands on almost every page which is really cool, they fit in and are not distracting, a lot are clickable links.
Sponsor links are kind of distracting. But for your comfort they tried to hide as many as they could at the Very Very Very bottom of the first page and the sponsor pages, It is a great site all around. The back ground is just a little loud but you can easily ignore it. Well I suggest that everyone check it out.
There is also a Store that you can get CDs and some DVD’s from which takes you to a different site ( http://www.musiChristian.com)
Some bios are shorter, some none, some tons, just depends.
