I don't like it...
...but god damn it I'll give it a decent review because nobody else can.
I didn't think the music really fit with the lyrics or the theme. Since your listing off names of pokemon i'd imagine that the music would be based off a theme from the pokemon series. If the music was... then thats a shame because i didn't recognize it. Pick something more obvious.
The lyrics weren't exactly that impressive. It was simply a list of names of pokemon that rhymed with one another. Its not a bad idea, but it was done poorly, particularly the voice. If thats your voice, then I am deeply sorry: it isn't a voice for singing nor rapping. It simply sounded bad.
All in all, I'm glad that someone did something relatively creative, even if it was poorly done. I put effort into my review because i can tell you put effort into your work. Make more. Who knows. Maybe you can prove me wrong. I hope so.
