Let's see here...
Mario Tennis / Mario Golf - I never heard these, but I loved Sakuraba's compositions for the GBA games, so I'll assume the GBC ones were worthwhile.
+2
King K.Rool / Ship Deck 2 - OH YES DO WANT.
+5
The Dark World -
+3
Theme of Samus Aran, Space Warrior - One of my favorite themes, and I was always disappointed that you could only really hear it at the end. Very nice!
+3
Opening / Menu (Metroid Prime) - This will be awesome to fight to.
+2
Gourmet Race - I haven't listed other songs that were already in the series, but it's by Sakuraba this time?
:O
+4
Boss Theme Medley (Kirby Series) - Marx, please? I won't give out a score since I don't know what's in here, necessarily.
Star Wolf - Excellent choice.
+2
There are more in here that I probably love and don't know I love because I don't remember them off the top of my head. But sadly I can't go looking for those because I have to wake up at like 4:45 AM.
Oh well. Time to slap together some stats and call it a night.
