Are there Chinese language-learning karaoke videos at a basic conversation level? I noticed that watching karaoke videos accelerates learning Chinese characters, even though you might not understand the characters fully. Is there a list of Mandarin and Cantonese karaoke videos for kids to learn characters?
Karaoke is more like combining the MV and lyrics together, most of them afford the instrumental version, which means that you can find them in Music Company. Of course, there is a faster way, if you know a karaoke store owner, he/she know how to get you a list of karaoke. 

FYI -
Most karaoke videos are properties of music companies, but due to some reasons lots of people have access to the pirate. So you might need to be cautious to avoid the legal issue.
