I'm betting your soundtracks would make the pianist's life easier, if you had the soundtracks playing through the church's speaker system, then you can just sing over the MIDI or whatever software you use.

Also, it is good that you have a Christian playlist. Hopefully Lauren Daigle is on it.

She has a very good voice, and is genuine. Some modern Christian songs in the mid-2010s kinda sounded like commercialized pop radio music of the time, but thankfully that era is phasing out in the 2020s. I like 2000s Christian stuff such as Matt Redman, Toby Mac and The Newsboys the most. Wish the radio played them more often. But hey, at least we get Lauren Daigle and similar, wholesome artists popping up. So, 2000s and 2020s good, second half of the 2010s not as much.
