If you can't hear the difference between a 3/4 and 4/4 style, it is just because your EAR hasn't been developed well enough yet. It just takes practice
listening to be able to tell when something is off. With enough practice you can even hear and figure out the chord changes and when they occur in any song.
I remember when I just started out on guitar and arranging music for my band, my lead guitarist pointed out that I had missed hearing a repeating minor chord in the song. I inserted the minor and he was correct, it sounded much better. I asked how he figured out that the minor was used there in the song. He replied, " I can hear it." I thought to myself, how in the heck do you learn to hear that minor? It just took practice, practice, practice (and time).
I have transcribe literally thousands of songs in my life time. I enjoy doing it as much as playing the songs. You had to learn to do it yourself before the internet came along. Today I find many of the transcribed music are missing chords that I see online posted (probably by people just starting out learning). But it is a good starting point and easy to fix them up, so it is a time saver.
