SimpleYoutube2Mp3 can download videos from YouTube and convert them to MP3 with the click of the mouse.
For our tests, we copied and pasted a link to one of the MajorGeeks tutorials and SimpleYoutube2Mp3 immediately picked it up detecting the name, uploader, and length. Pressing the arrow button begins the download and conversion. Our seven-minute test downloaded and converted in under a minute. Finally, a folder appears to open the folder your converted files are in. You can enter multiple videos and either click the X to close them when done or save them to a .txt file that can be loaded later.
There are some basic settings including the download locations, automation, and notifications. A history tab is also available so you can always see what you pasted into SimpleYoutube2Mp3.
If anything is lacking, it's the ability to define the quality of the MP3 output. In some cases, you might want lower quality and in the case of music, best quality, especially with YouTube because the quality is often cut at the expense of speed. The option to watch and clipboard recently viewed YouTube videos might be nice, although that could be a memory hog. Finally, we must complain when there's no portable version available.
Regardless, SimpleYoutube2Mp3 was fast and easy to use as promised.
