It's an interesting decision for her to put an audiobook on her album - maybe trying to prove to her hatres that she can read? I found that the backing music is a bit too loud and energetic to focus on the story being told, but thankfully there's enough repetition that it's easy enough to follow. I'd recommend choosing a story with more to it next time as even Timomatic's concept album had more to its story than this, but it's good for a first try.
Reviewing seriously :P, it's full of cool drops and the beats are pretty enjoyable throughout. I did find it a bit tiring in the last 10 minutes or so, which is probably down to me not being the intended audience for this (either because I don't normally listen to long megamixes, or because it's made to be heard in the club or during a workout or something that doesn't give full attention to the music [which, for the record, does not make it inferior to music designed for more attention; just for a different purpose]) - however I do still think it would've helped if she went through more than six songs*, as I don't think anyone is really interested in already repetitive songs stretched out to several times their lengths. Regardless, I think Havana did well with this, and I think it does well at showcasing her DJ skills that don't come through in like any of her singles. 4.3* from me.
* If anyone's curious, these are the songs (since it doesn't seem to be listed anywhere): "Flashing Lights", "Big Banana" (begins around 12:00), "Spread A Little Love" (~19:50), "You'll Be Mine" (~27:15), "Get It" (~30:45) and "We Run The Night" (~36:30).
