Mark yes I am aware you can find some karaoke on YouTube... problem is you have to deal with adds and dead space so you can't rely on it for live.. and you can not download the karaoke file..
I already have more than 100,000 karaoke files... the advantage of Karafun2... and the subscription... you don't need storage space as long as you have an internet connection..
Other benefits.. all 30,000 of Karafun's songs have a melody track that you can adjust volume to help you learn a song ..also background (vocal) track with separate volume control..
You can also link your computer library, but I find the Karafun library is all I need... and I have a very large library to start with..
The service price is worth it... Give up two cups of coffee at Starbucks.
