おやすみポラリスさよならパラレルワールド／ギラメタスでんぱスターズ（通常盤）

The instrumental of Ψ発見伝！ alone is worth the price, it’s such a banger on repeat. All three main tracks have that chaotic energy I love, and the audio quality on the disc is crisp from start to finish.

I've been playing the instrumental versions on repeat for my morning commute—they hit different without the vocals. The energy on "ギラメタスでんぱスターズ" is absolutely infectious, gets me pumped every time.

Track 3 "Ψ発見伝！" is such a hidden gem, with that catchy synth hook that gets stuck in your head for days. The instrumental versions are a nice bonus for practicing the vocals or just appreciating the production.
