Can anyone advise me a proven way to convert YouTube video to mp3 file? I need to download a couple of songs. I found several services, but they greatly spoil the quality of the music.

This is exactly the problem. I also wanted to find some songs that I only heard on YouTube, but the quality is terrible. I don't even want to listen to them with headphones.

Guys, for a long time there are different services for converting music, but at the same time maintaining high quality. I don't think there are any problems with it now. Try mp3juice. I think that this free service is really cool, because it's a cool opportunity to convert any video from mp3 file at all. In addition, when converting, the quality of the music remains at the same level which is cool.
