Anders SG of Alphabeat told Atitude Magazine that this song was especially inspired by Black Box's 1990 hit single Black Box's " I Don't Know Anybody Else ." He added: "It's a fully-fledged dance record." (Source The Spell Songfacts).
Seriously though, if you like 'The Spell', listen to [url=http://www.last.fm/music/Black+Box/_/I+Don%27t+Know+Anybody+Else]'I Don't Know Anybody Else'[/url]. The 'About This Track' above says it was an inspiration for 'The Spell', but Alphabeat pretty much copies it as much as you can without breaching copyright. Albeit in an AWESOME way.
