Sonic Runners' soundtrack is really great and the favorite of many, so why not replace some music in Mania with the Runners music? This mod replaces a few songs in the game with music from Sonic Runners, but I cheated a bit and also included some from Lost World (I found it fitting since most of Runners' levels come from Lost World). I couldn't include all the tracks from the game because I couldn't find some tracks that fit with certain levels, but the mod may get updated to add new tracks.
