I loved the song, and the video. It's amazing that the vocals are synthetic; I would have never guessed.

As for the English "Don't put me on a wall..." It doesn't really mean anything specific to me. While it's a bit different than putting someone on a pedestal, putting something on the wall suggests hanging a trophy. So, simply changing the "a" to "the" could be a fix. The meaning would change a bit from 'don't over-idealize me' to 'don't consider me your possession.'
