Kat found this 5KPlayer program này FREE on internet, downloaded xuống computer and now I can convert any Youtube to MP3 so I can listen on my phone or download any YT video to your computer for later viewing. It's safe, just wanna share. You can google 5KPlayer and download it if interested.

Chời ơi sao hông post cái link dùm Kat ....

Here you go anh:
