Pop icon Lady Gaga delighted waiting fans last night (July 22) by blasting part of a brand new track through her car's stereo for them to check out.

Although the superstar hasn't revealed details of the song's title, several of her followers who were treated to an advance listen took to social networking site Twitter to write about the experience.

User @PrinceAirik wrote: "GAGA JUST STOPPED FOR US BLASTING A NEW SONG!!!! It wasn't nothing on but the radio ! it was another song i've never heard before..."

He later added: "it sounds like her voice is super auto tuned in the song.. i can't explain it"

Fan @boyXsupreme was one of the lucky people to hear the cut and he explained: "Gaga didn't tell us the name of the song she was playing for us (obviously. why would she?) but it was clearly from the new album.

"IT WAS VERY HARD TO HEAR THE LYRICS CAUSE EVERYONE WAS SCREAMING BUT YOU COULD HEAR THE BEAT AND THE MELODY AND IT WAS F*CKING INSANE!!!!"

Another Twitter fan (@An_niee), who also uploaded a photo of Gaga that can be seen below, shared details of the impromptu meeting: "It had such a sick beat and it was a major dance song!!! I asked her if it was the new single she looked at me and shook her head yes and said shhhhh."
