O Replay Media Catcher pode fazer isso automaticamente.
The Replay Media Catcher software can capture any form of audio and video media found on the web with a click of a button – saving you hundreds of dollars in the long-run for you music lovers out there.
What this means is that you can be watching a music video on Youtube and with the click of a button, have the entire video on your computer in a matter of minutes. Or if you prefer, you can choose to only capture the audio from the video and have the mp3 file on your computer almost instantly.
