Not really favorite 'songs' but anyway... Two sets from the SonneMondSterne Festival in Saalburg, Germany, August 2002, where Underworld played too. Heavy rotation in the past six and a half years.
Anthony Rother
Straight-forward, solid, danceable techno, plus 'machine-speak' lyrics.
Northern Lite
Catchy pop-rock techno, plus spoken-word lyrics, plus guitarrrrrr (!).
