Youtube-MP3 Converter is an application available for Mac, this application supports open source to download mp3 from YouTube this application. Users who want to download YouTube music, just copy the link, then paste it into the YouTube-MP3 Converter application. then you can convert your mp3 directly. so users do not need another application of hidden music.
The application has only the option to download music. my suggestion is to have a video download and history page option.
The user will not only be able to download music but also videos. history page can see past transactions. as a result the application will be more useful and efficient
