Azs 920 Cu Note Patched | Imnuri Crestine

I need to consider who the target audience is. Since it's in Romanian, the audience is probably Romanian speakers interested in spiritual or religious music, maybe Christian hymns. The AZS 920 might refer to a specific version of a hymn collection, possibly in a certain key (like A minor or D major?), but I'm not sure. Alternatively, AZS could be an abbreviation for something else.
