"Emerald Shore": Greg2k: song Comments

"Green Hill Zone": 8 Bit Instrumental VGM: song Comments

"Mario flys in and hits link round the head with a deku stick" (violent-sounding title but the song itself is nothing like that): infamous: song Comments

"The Forest That Never Sleeps": halcyon: song Comments

"Mushroom Maddness": Trevin Hughes: song Comments

"Pilotwings!": Hezkore: song Comments

VUREZ.COM - I haven't listened to all of these yet but I can recommend "Wind Swoop" and "Flaming Desert Sand".
