Let's start with the unknown IDs of the bunch: tukema, anan, 55yuo and cancan. These seem completely new, unless they are coming from the new Taiko 0.5 or Taiko 3DS.
But wait a minute... there is something on the bottom of the first picture... doomn? That's right: the infamous Game Music Doom Noiz from Galaga Legions is going to freak the PSP players soon! Now to try it on Detarame modifier!
UPDATE: 55yuo is confirmed to be Go Go Yuureisen, one of this month's Variety songs.
ponpon easily suggests another console porting of PON PON PON, a J-Pop song by Kyari Pamyu Pamyu.
Last but not least, another known Namco Original is going to approach the portable scenario with its Ura mode! After its recent arcade porting, Metal Police (ID: metro) and its Ura mode from Taiko Wii 3 (ID: exmetr) is coming to PSP, hopefully free of charge.
