Hello there! Question toothbrush here!
I have a serious question:
is there a guideline when a person should start transcribing music after he or she done enough of preparation on these exercises in TG?
Also, second question: what is average complexity of different genres, so I won't get destroyed by complexity of jazz for example of it's play with scales, borrowing chords and other stuff.

Even if we talk about electronic music for example current Riddim Dubstep or current EDM trap, you might discover that a lot of producers use Phrygian mode for making dark vibes or just use a lot of accidentals that don't fit into a certain scale.

Where one with these skills gained in such website as TG should go next?
I have a problems, for example, people say that most popular music based on 4 chords - I, IV, V and vi degrees of a major scale, but every time when I take a song that interests me it deviates from that pattern.
for example a song might use iv chord instead of a IV chord, so many other possibilities even in current pop music.

Here is an example I took today.

This song was big in EDM and it's Amin. It uses III - IV - ii chord progression

I have only been transcribing for the past couple of months so take what I say with a grain of salt.

1) start with just melodies. There's typically a lot less going on in a melody than in a harmony its easier to figure out
2) figure out the bass. Bass is the next easiest thing to hear in a song and will give you the structure

Harmonies are harder to figure out and take more music theory than hearing ability in my experience sofar.

The easiest songs in my opinion are Folksongs and cheery pop songs. very little going on there usually. Lots of modern rap songs also just do a iv - i progression so not a lot to think about there.

I would like to point out that III -IV - ii would be correct if you are to say the song is in C major, but it is in Amin as you said and the G# you are hearing in the E is because in minor you have a raised 7th to get a semitone leading tone ( in this case G# to A) So actually the progression is V-VI-iv
