Taiko no Tatsujin Wii Kettaiban Music List?

I know this game has like over 100 songs, and some are gained through unlocking in-game.but on Wikipedia it only shows like 30 songs and it says that the song list updates monthly,
so does that mean it has a form of DLC? I want to know this before I buy it. ;DP.S.
is this game 4 players?
my family needs a new "family night game"

I got on Google for you and these are the links with a song list I found:http://en.wikipedia.org/wiki/Taiko_no_Tatsujin_Wii:_Kettei-Ban

Thanks for your reply,
but I've already looked at those places though.When wikipedia said that it doesn't use "downloaded songs" it meant
that the game doesn't download individual songs anymore, like previous
Taiko games would.Well, I already bought the game and played it and most of the songs
were indeed unlocked by playing more, so I guess the part where it stated
that the list updated monthly was misleading.
