I just today downloaded all of the Little Big Town Albums. The strange things is that the version of Other side of the bed has a totally different vocal sound on my iPad vs. the version on my iPhone? It's like one is more high pitched and has a totally different vibe. The other one sound exactly like the version on the video. I'm not crazy and I've let others listen to be certain.....lol! Are there 2 versions of this song?? Help!
