Per its name, The Billboard 200 is a weekly list of the 200 highest-selling albums in the U.S. The official soundtrack for Halo: Reach debuted at No. 157 for the past week, the best mark ever for the franchise.
Past Halo soundtracks have also hit Billboard's 200 - Halo 2 got up to 162 in 2004; Halo 3 spent just one week at 200 in 2007, and Halo 3: ODST spent one week at 179 last year.
Billboard notes that all sales of the Halo: Reach soundtrack so far are digital-only; the album's physical release is on Sept. 28.
But it is the first Halo soundtrack to crack the top 10 on Billboard's Soundtracks rankings, debuting at No. 8.
