Good music?

I have been listening to John Mayer alot the last couple days, and I find his music very relaxing and nice to listen too. I tried to find artists similar to him and Jack Johnson came up. Does anyone know anything about him? I did a quick search and Im not sure if he is a Christian or not, but I would like to know if any of his songs have immoral things in them or go against Catholic teaching. Thanks
