This is a non-30-minute version:
It's ok, I'll do it.
30-minute videos can sometimes make things easier because the arranger doesn't have to restart the video over and over again.
Actually, I download the mp3, so I can put that into Audacity and be a lot more accurate (since I can do whatever I want do the audio, sometimes it's useful to raise or lower by an octave for example). A 30-minute version would just be a longer download for me, I would cut it when I put it into Audacity.
