Why do we need to add Youtube Kara search postfix keyword?

1.You can find your postfix of Youtube search from the upper right corner(inside red rectangular):

2.The above figure shows +karaoke, it means when you choose any singer in youtube kara List, it will search the youtube website by using "SingerName  karaoke"  keyword.

3.You can also try "Do not append"，that means only use singername to search, so the result will be different.

4.You can switch Append / Do not append before you do the karaoke song search.

Notice: The Youtube Content is subject to change without notice by Youtube, Hence it may lead to Bluekara can not access those songs with limitation by Youtube.
