Kero Rhythm - VGMdb (http://vgmdb.net/album/45734)
Kero Blaster & Kero Rhythm (http://www.playism-games.com/games/keroblaster/)
Can anyone please upload this soundtrack?

Also looking for this.

The Kero Blaster & Kero Rhythm bundle from Playism includes a horrible quality copy of the soundtrack. The set consists of 64kbps stereo 22kHz MP3 files and the music sounds terribly compressed compared to the in-game audio. I don't know if the standalone Kero Rhythm soundtrack is any better since I refuse to give Playism any more money to find out. Playism blatantly lied to me when I reported the problem to them by falsely claiming that "the mp3 audio files are actually the exact quality in the game." So, it would be outstanding if a high-quality copy of the soundtrack for this game became available.

Just bought the standalone OST, and yes, same low (but acceptable) quality. Still, i wanted to support Daisuke Amaya / Playism.
Luckily, Pixel released a simple player for his own music format, complete with wave encoder.
I'll open a new topic soon with my 320kbps recording ;)
