Once released, the song peaked at number 31 on the UK Singles Chart, Oasis's lowest-peaking single.

It did amass sales of over 215,000 over time, making it their 13th biggest selling single ever in the UK.

Speaking to Spin magazine, Gallagher recalled writing the song high on drugs:

I was a roadie for three years with Inspiral Carpets. What do you think I was doing then? Drinking mineral water and eating Twiglets? The whole of the first three albums were written on drugs. I remember being off my nut and going into the back room and setting the goal of writing a song in ten minutes. That was "Supersonic."

The song appears on their debut album Definitely Maybe, released in August 1994.

It was also the band's first single to chart in the United States, where it peaked at number 11 on the Billboard Modern Rock Tracks chart.

Q magazine has placed "Supersonic" at number 20 in its list of the 100 Greatest Guitar Tracks in 2005.

In the lyrics to the song, a reference to "Elsa" was apparently due to a nine-stone rottweiler with a flatulence problem.

The dog belonged to the sound engineer Dave Scott and was in the studio on the day the song was written, hence the line "she's into Alka Seltzer".
