According to my site meter statistics, a lot of gospelgal.com readers first encounter this site through search engines as they look for lyrics to their favorite songs. (You mean you didn't come for the insightful commentary and trenchant observations you find here?)
LearnGospelMusic.com has a page where you can search for lyrics and chords. If you can't find the info you need there, you can post on their message board to get some help. So happy searching, and tell them Gospel Gal sent you.
If you know of some good sites for lyrics, chords and sheet music, why don't you leave the URLs in the comments section. If we get enough, maybe I'll post a roundup entry with our collective findings.
