Go! Go! 575 adapts the Project 575 games for PlayStation Vita and iOS, which allow anyone to create songs using the traditional Japanese 5-7-5-syllable meter found in haiku and tanka poems.
I just noticed that I have this in my computer so that's the main reason why I watched this ^^'. There is only 4 episodes and they are only 3 min long so you can watch this anime only in 12 minutes. And if you remember what I said about Onee-chan ga kita -anime. You probably can guess what I think about this. This is too short in every way in my taste.
