Great, Pokemon songs are epic win.
That must of took ages...
Ok, here's my shot on what I think the songs were:
Bicycle - Pokemon Red & Blue
Littleroot Town - Pokemon Ruby & Sapphire
Route 38 - Pokemon Gold & Silver
Lilycove City - Pokemon Ruby & Sapphire
Pallet Town - Pokemon Red & Blue
Verdenturf Town - Pokemon Ruby & Sapphire
There we go. I personally would have preferred more GSC songs, I think they had some of the best tracks out of all the games... but still, this compilation was just amazing. Should have way more listens. Awesome work!
