Find someone in your community who has professional map tech skills. That person can get detailed map data from your municipality and upload it into openstreetmaps, and you will then have the best maps :) if you are so inclined, you can learn yourself from their site.
I don’t know how well it scales, but I find Metro to be rather good. Find it of f-droid.

It also shows lyrics at a touch, if they’re in the metadata, and apparently recognizes lyric synchronization if it is there.
