Sorry for how long it's taken me to respond to this (just been trying to keep up with emails and get the next updates ready). If you all sync to the same Google Drive folder, I actually think this is going to be a problem. The main reason is that the song ID linking functionality is also used by the library sync feature. So that could cause the wrong songs to be synchronized on each device. What I think you'll have to do is something a little more elaborate. Each version of a song (with capo/without, etc) will need to exist as a separate song in the library. Each user can select on the "Connect Devices" dialog how songs are matched (tap "Settings" and change the "Match songs using" field). If you match on Custom or Custom2 and use those fields to assign matching numbers, then the library sync will still work correctly, but you can link together different versions of songs on each device. By each user being able to utilize Custom or Custom2, you can at least match on two different songs from what is on the master. Let me know if this might work for your needs. If not, we will need to brainstorm what kind of changes are required.
