Dirpy is a free web application that allows you to convert YouTube videos into high quality MP3. You can start by searching for YouTube videos on Dirpy, or if you already have a YouTube URL, just paste it and click on Dirpy.

Dirpy will convert that video into a high quality MP3 file and then let you download it. It also provides you direct links to different YouTube qualities of the same video such as Low Quality and High Quality.

The application is no doubt quite useful, but some work is definitely needed to make it more user friendly.
