"Interstate Love Song" is one of Stone Temple Pilots' biggest songs. It was huge on the various "Alternative" radio stations that were cropping up in the early '90s, and it also got a lot of airplay on Top 40 stations, where it shared space on playlists with the likes of Gin Blossoms and Sheryl Crow.
At this time, the band's songs weren't sold as singles in the United States, which encouraged album sales. Their label, Atlantic Records, still meticulously promoted the singles to radio stations in an effort to keep STP on the airwaves as long as possible. Purple
went to #1 soon after it was released in June 1994, where it stayed for three weeks. "Big Empty
" was the first single, peaking at #50 on the Billboard Airplay chart in July 1994 (Hot 100 rules at the time made songs that weren't sold as singles ineligible for the chart). "Vasoline
" went to #38 in August, and "Interstate Love Song" made #18 in December.
