しゅきしゅきしゅきぴ♡がとまらないっ…！（初回限定盤）／ねもぺろ from でんぱ組.inc

The instrumental versions let me actually hear the production layers in these tracks, which I didn't expect from a single. That making-of footage on the DVD is a nice bonus too—fun to see how the music video came together.

The making-of footage on the DVD is such a fun bonus, really lets you see the energy behind the recording. The B-side “夜ふかし乙女のドキドキはっぴぃでぃず” has been stuck in my head all week.

The music video DVD is what sealed it for me — the making-of footage is way more charming than I expected, and the A-side has been stuck in my head for three days straight. Even the instrumental tracks get played around here, which never happens with singles I buy.
