Ever since college 45 years ago, I've been transcribing chord progressions. I haven't found anything that gets me even remotely close when analyzing the Brazilian jazz stuff I play. <...>
Jazzy stuff can be very difficult, especially when you get extended chords or one chord stacked on top of another. That's another reason why I prefer to get the sheet music.
If I can't get the sheet, a PGV book followed by a fake book can be good.
If I have to, I'll use my ears, and that will often get me either right on or close, depending on how complex the music is. If I'm going to use my ears, I'd prefer an uncompressed copy of the music. YouTube, mp3s and other compressed formats often leave out some of the notes if they are not played loud enough.
I do know there are times when you have to go with 'that's good enough'. However, if it's going to be a backing track for my duo, I'm hopefully going to play it thousands of times, and so any time I put in to make it better is worth it. If it's something I may be selling on my site, it has my name on it, so any time I spend making it better is not only worth it, but a source of pride.
But like I said, that's me. What's right for me might be an overkill to another - and my way is not the only correct way to do it.
