Most of the time, I prefer the original version of a song to any remixes that follow it; however, sometimes there are exceptions. This is one of those songs:
It's the Melou Remix of "Just One Day" by the Mighty Oaks. The Mighty Oaks are a German band, although its members are American, British and Italian, respectively. I came across the Melou Remix by accident on Soundcloud; funnily enough, I was linked to it after coming cross another song that I'd heard on SoundCloud by chance.
The original version of "Just One Day" can be found here. The original is still an awesome track - I just happen to prefer the remix.
