Oh man, lessee... as you have probably guessed I'm mostly stuck in the 80's.
Petra (with John Schlitt formerly of Head East), Kerry Livgren and John Elefante (both formerly of Kansas - still praying for my fav vocalist Steve Walsh), Allies (probably the heaviest Christian rock I listen to), MW Smith, SC Chapman, Amy Grant's early stuff, Michael Card, Bob Bennett, Russ Taff (love his smoky voice - I'm an ex-singer so favor vocalists), Sheila Walsh, Mark Farner (formerly of Grand Funk), Jon Gibson (funky like Stevie Wonder), Benny Hester, Twila Paris, 2nd Chapter Of Acts, Steve Camp, David Meece, Bryan Duncan, Degarmo and Key, Margaret Becker, Leon Patillo, Rich Mullins, Keith Green (reading His biography now - what a gifted man of God), Kim Hill, The Imperials, Gaither Vocal Band, Don Francisco, and on and on.
More modern... love CeCe Wynans, Charity Gayle (I can't listen to "I Speak Jesus" enough lately!), Don Moen, Leeland, Hillsong Worship, Elevation Worship, Lenny LeBlanc, and ever-expanding. I put on a varied playlist most nights to go to sleep and learn who the artists are over time.
Aren't you glad you asked, ha? Like you, I'm a major music fan. I'm trying to catch up with yours a little at a time, but boy you crank em out! Do you get your favorite new artists from your collection or from YouTube like I do?
