I already ordered 7 becuase it's the newest version and I liked the song list for it(zomg, hare hare yukai? HELL YES

)
People say 5 and 6 are also worth getting it but I have no idea becuase there aren't any song list for it. And I'm trying to get a drum controller but one that play asia offeres comes with TnT version that I don't think it's that good based on what I read so far. So, I'm thinking of getting one in ebay(bundle pack with TnT: Drum master is around 20~30 @_@)
And I asked this earlier but which version of TnT has Sakura by Ketsumeishi?
Thanks
