"emotional technology" spent 25 weeks on the "billboard" dance/electronic albums chart, reaching the top spot, and it reached #138 on the "billboard" 200 charts. the biggest single from the album, "somnambulist (simply being loved)", draws heavily from the breakbeats and new wave dance of new order and depeche mode, whom bt has cited as major influences.
