Konami is expanding Pop’n Music Portable 2 with downloadable song packs. The first one is available now and it has a treat for Castlevania fans.

Arriving fashionably late, Konami finally released the promised Pop’n Music Portable 2 demo on PlayStation Network. You can download the trial version for free from Japan’s PlayStation Store.

Bonus songs include a track from the upcoming arcade game Pop’n Music 20 Fantasia.

Curious about the Pop ‘n Music series, but don’t want to import a game without trying it first? Konami will solve this conundrum by releasing a demo of Pop ‘n Music Portable 2 on PlayStation Network in Japan.

Konami’s sequel to last year’s PSP rhythm tapping game has a media install feature, training mode, and downloadable music.
