"Moaner" is a song by Underworld. It appeared on the Batman & Robin soundtrack first, and was later edited and added as the last track to the album Beaucoup Fish. It was only released in Germany and the US. The UK imported the German releases. The single peaked on the UK Singles Chart at #89. The song's bassline was ranked by Stylus Magazine at number 27 in their list of the "Top 50 Basslines of All Time". However, the same article mentions lyrics which are in fact the lyrics to the track "Push Upstairs". It might be this track that they are actually referring too.
