Awesome rhythm game
A great pick-up-and-go game, I started playing it on the bus as soon as it arrived. You can play many variants of a song by playing the different instruments, and there is also an interesting 'survival mode' you can test your skills with.

However, the midi quality of the songs is a bit of a turnoff... though the gameplay largely makes up for it. And don't forgot 8 player wireless!

BEST GAME EVER!! I'm so hooked!
This game is one of the reasons I bought a DS Lite. It's true it may not have the best visuals like the Bemani games, but what it lacks in that department makes up for the overall gameplay. (It also helps that it has some of my favorite J-pop songs in the game) Also, for all you instrument players, if you have a favorite piece of sheet music, you can input songs in the editor and then play them as you would any of the featured songs in the game. BUY it! It's worth it.

Still a great bemani game
I am a big fan of bemani games, so i got DJ MAX for PSP (great game, if you have one, buy it). I was really happy to see that there was a bemani game for DS where you could write your own songs. It was one of the reasons i even got a DS. When i got it i started playing it directly. It really is a fun game. I have played it for some time now, and haven´t gotten tired of it.

The best part is multiplayer. Up to eight players can play your creations with one game card. Of course you already know that. The only bad thing about the game is that you can´t change the time signature of your songs. It´s a small flaw for a great game. If you haven´t got it already, buy it.

It's really good!!
This is a really fun game!! I would liken the game to Beatmania, in that you have to press certain buttons at certain times, but in this case, you're actually playing the instruments featured in the songs.

The songs are great, and deserve to have an English version. But, for the time being, this is a fantastic start. The game-centric songs are easily one of the best to play through :)

Fun but could be so much better
Bad:
- mostly bad music
- almost unbearable instruments sounds (think old midi crap on the PC 15 years ago)
- no high scores or stats
- poor visuals during game

Good:
- challenging
- fun
