When I’m doing that I use a program called Transcribe! It has every feature you could want for this purpose, really. You can mark off the individual sections, measures (and beats if you want) and take notes, looping them at any speed you want (with pitch correction), and it even has a tone generator you can use to check your transcription. It’s $39 dollars and well worth it. One time I sent the author an email and they promptly responded with great answers to all my questions.

I do try to do it the old fashioned way first, though. I’ll pull the song into Reaper or something and just play along.
I have a bike I put together with this mindset and it’s pretty awesome. If any component dies I can replace it individually, even if it’s not made by the same company. No reason an electric car couldn’t have the same benefits except that the average consumer doesn’t care about planning ahead
