perhaps a bigger issue than posting covers is that of selling karaoke tracks. You may be opening up a bigger can o' worms there than you can eat at one sitting.

I don't know what the legality of the disclaimers we all agree to when we click that little ol' "I AGREE" button every time we join one of those streaming sites... but basically they all protect the site from legal responsibility for the posting of copyrighted material. So, when you click "I AGREE" you are basically saying that you accept responsibility for your own interpretation of copyright law.

I have to think these agreements were drafted by lawyers, and would stand up in court, if it came to that.

The million dollar question is whether a small fish without deep pockets would be worth suing. Your call.
