The OSTs of those two games as stated in the title of the blog post have the extended versions of the songs, if not, different versions and to view those exclusive tracks, you have to buy those OST CDs. Surprisingly enough, Beatmania IIDX 20 Tricoro OST has the international release although the dis-guarantee is that there are apparently some Japanese songs in that version despite the credit changes for the US/EU version. So, if you're not the fan of the genre or perhaps the Bemani games, then what's the point of buying that soundtrack as a westerner. But if you are, then that will be the one for you as the series is as popular as ever in the arcades in the east.
Now, about the Lincle arrangements I made, all of those except Wonder Walker are surprisingly using the 16-Bit soundfont. You can check those out in my YouTube account. However, to be frank, not all 16-Bit arrangements I made are credited to TheEightBit as I don't want him to think that I've gone too far like using that soundfont for something else. Apparently, I also used the soundfont for arranging certain Vocaloid songs that are in today's Sega rhythm games. But if the song names I arranged in 16-Bit form are in English, perhaps I can guarantee a smooth crediting to TheEightBit.
