This TIDAL “hi-fidelity music streaming” thing is actually happening. Not formally acquainted? Well, allow me to introduce you. A group of 16 mega-star musicians and/or musically-inclined entertainers united in a noble effort this past Monday to launch a music streaming service that offers audiences music with CD-quality sound, videos and other "exclusive" content the way artists like Jay-Z, Beyonce, Kanye West and Rihanna originally intended to--for a fee of $19.99 a month, of course. The whole idea is to protect the integrity of the musicians' work, while compensating them more fairly for consumption of the art. That all sounds fantastic, and although Hov, Coldplay and Madonna aren’t your typical charity cases, I extend my deepest sympathies during these horrendously trying times in the music business.

If you are considering a TIDAL subscription, here are 5 things you should know.
