A+ This thing is insane. Like almost perfect. I was skeptical at first but man it does it do the thing. Two small gripes but I suppose it can't be perfect can it?One, it opens a new tab and you have to select which quality. Two, you have to tell it to download after its made the mp3. Perfect version of this app: allows you to auto set a quality and auto download the mp3 after conversion without opening a new tab. With that as an option, it would be UNSTOPPABLE ya hearrrrrr. A++++++++++ if you could figure out a way to do batch youtube videos like from a playlist
