The ballad "Lost in You" by Chris Gaines, the Garth Brooks [ tickets ] alter-ego created for a future feature film project about a fictional pop/rock star, shot from #152 to #2 on SoundScan's Top 200 singles chart this week. It's the first commercial single from the album "Garth Brooks in ... The Life of Chris Gaines," (Capitol-Nashville) which will be released on Sept. 28.

The flip side of the single -- another album track titled ''It Don't Matter To The Sun'' -- hit #1 on Billboard's Country Single Sales charts last week.

According to Brooks' label, SoundScan reports that ''Lost in You'' racked up sales of 107,214 units for the week. The song has been receiving heavy airplay on Adult Contemporary, New Adult Contemporary and Top 40 radio stations.

The forthcoming album will be accompanied by a continuation of the media-blitz already in progress. Brooks just finished taping an NBC special, ''Garth Brooks in ...
