To be honest Donkey Kong Country series was not my cup of tea. It was a straightforward platforming game released as one of the first SNES games and it featured some crazy (for the time) pre-rendered photo realistic graphics. It was enough to make it an awesome game, but it has not aged too well gameplay wise. It's just really simple; a bit too simple for me. I think it's partly because I never got to play SNES games until I found out about emulation and by that time I was spoiled by more modern games like PS1 and N64 stuff. TLDR: I don't quite hold DKC series on such high pedastals as others might, but I love the one song from the series in particular..
And the readers that follow me and played DKC2 will all go "OMG YES, THAT SONG" in unison because it is that powerful of a song. DKC2 has some good songs, but this definitely takes the gold medal hands down. It is relaxing, soothing, and it has a mysterious tone to it. I really hope you give this a listen if you're having a bad day as it might make the rest of your day pretty mellow.
