Judging by the posts we've received, the current favorite song from the finale is I've Got to Find a Way. Warhok97 shared his cover version of the song, and it sounds fantastic.
Listen to Warhok97's version in the video. It is really faithful to the original. What's more, he worked it out by ear, which blows me away! You can find Warhok97 on Youtube and DA.
Thanks for sharing your cover!
