Listen to any of these songs/composers every day for a great uplift. (I can't say that all the videos are super uplifting or as modest as I would like them to be, thus the emphasis on "listen". Most of them are pretty good, though. And I can't vouch for all songs by all these artists being good.) At some point I will organize these in categories and add lots more songs, but here is a good start for you.
Next to the word of God, music deserves the highest praise. The gift of language, combined with the gift of song, was given to humankind that we should proclaim the Word of God through music. ~~Martin Luther
