You're right AJ, and that's why, within the confines of this small group, we have to rely on CONSENSUS. Based on that, the ratings would be:
1. The Lucky Peterson version
2. The SUNY Soul Voices choir version
3. .
4. .
5. .
6. .
7. God-awful choir version
8. The Arranger version

Not a knock on the instrument but the lack of rhythmic feel (syncopated rhythm) and the 'mechanical' nature of it, make it a 'no-go' for me (but I admit, it's subjective). There's also some missing chord interplay that's integral to the feel of the song (may not be possible on an arranger???). JMO. If it were me, I'd try to find a suitable drum pattern, turn off the auto-accomp, dial up the best piano voice, and play it manually. But that's just me.
