For those finding an interest in Denpa Henkan On Air, Rockman Perfect Memories is offering the complete soundtrack for download.
For the most part, the songs are upbeat and very catchy. It holds up well alongside other songs in the Ryuusei/Shooting Star series. Of note, a few tracks contain sound effects in the background as a result of recording. It might annoy some but if you're like me, you can easily ignore it.
