If you play through/listen to every video on the channel my mate said you could develop perfect pitch, well really good relative pitch at least and your pitch memory would probably get pretty solid as well.
No guarantees though, you might not focus enough and that's on you.

Yea max quality is 360p, don't need this in high def really and that's saving YouTube space and your bandwidth, so winners all round.
