Here's a few great examples: Mother 2 from Earthbound. https://www.youtube.com/watch?v=_e_GqFqq0_w Sounds like an opening to an Anime, but it's one of the most upbeat and happy songs I've probably ever heard, quite amazing in fact. Battlefield: https://www.youtube.com/watch?v=eNs5ei6xUhM My memory is a little foggy on this one, but when you were doing Multi-Man Melees or story battles with a certain character this would play later on on a certain stage. Poke Floats: https://www.youtube.com/watch?v=xxdTM2GB2PM Classix medley of several great Pokemon themes like the Trainer Battle, Gym Leader Theme, and Wild Pokemon theme. Fountain of Dreams: https://www.youtube.com/watch?v=0wLoirmq8MU Amazing Orchestra arrangement of one of Kirby's most well-known themes. Fire Emblem: https://www.youtube.com/watch?v=HjRmdwGILfc The classic Fire Emblem theme, with some nice touches. Targets: https://www.youtube.com/watch?v=TXHQb7RN9lE Even though the Target Practice mini-games could be infuriating sometimes, at least the music is catchy. Big Blue: https://www.youtube.com/watch?v=9ZLi13Yk358 From F-Zero, I never played the original, but this re-imagining of it is amazing. The Mute City version is also out there as well. Final Destination: https://www.youtube.com/watch?v=UvfDISoyvWk Oh Master Hand...What a pain in the ass you could be. I like Brawl's version better, but this one is still superb. There are tons of others from this Youtuber, all extended to 30 minutes, check them out when you can.
