It's good!
Fantastic extension to a fantastic game. Pity that it doesn't save your score, unlike with the main DS cartridge, but the songs are well-worth the purchase.

Good game, but....
What's the name of the Janne Da Arc song? I only recognize the kanji for 'hikari' in the middle, and neither on the left or right. I don't have a song with hikari in the name(and I have 107 by Janne Da Arc) so I wanted to know what this was so I could complete my collection

No title
The tracklist is so great ! It's a real pleasure to listen exclusively japanese songs or nintendo soundtracks ! But...you can't save yours scores, too bad - almost perfect for Rythm Games lovers !

Amazing songs - but no score save?!
I love Band Brothers - in fact, I'd say its one of the best games on DS - every DS owner should have it..

BUT whilst this is a great expansion to add longevity to the game - why can't you save scores for the new songs?! Its ridiculous!

Bravo Nintendo for adding support for expansions from the offset - but a big no,no for removing the most appealling aspect of the game.

Saving
Yeah, unfortunately, you can't save your high scores.
I don't really care though, it's just a minor issue.
