Exactly! It is legal to download songs or videos from YouTube. If you bought the premium of YouTube, you can easily get the songs and Videos on your own device. But my friends told me that DumpMedia Video Converter makes sense. I tried it and it helps me download the songs and keep them forever. I am free to choose the output format in this converter. This converter is available to download the songs from many video sites not just for YouTube. You can try it.
