Can BIAB analyze songs well? I recently came across a song that I really like. But I heard some interesting chord progressions in it.
Some people think the song is Em-C-Am-D
Some people think the song is EMaj7- CMaj7- Em7/A - GMaj7/A - Em7/D - AMaj7/B

I don't know how to use BIAB to analyze. So I put this song here. Let everyone help me take a look. If you are interested, we can discuss it together. You can talk about how to analyze with BIAB, or just talk about song analysis.

This is the audio of the song. I share it here.
《LE SSERAFIM - Blue Flame》


This is a guy playing it and he used Em, but I think some of it is actually Emaj


Let's take a look at the others.
