Essential John Mayer tracks to check out

John Mayer had resorted to Botox.

In a recent interview with "Elvis Duran in the Morning" on Z100, the seven-time Grammy award winner described how the chemical most commonly associated with plastic surgery was in fact, the unusual therapy method that helped finally heal his damaged vocal chords.

"What I had was basically a blister, but in the worse place you could get it. It was right where my voice was banging up against itself," Mayer told the radio host.

"I had surgery [but] it didn't work. And what fixed it was getting Botox in my throat. It chemically paralyzed my vocal chords so it could heal."

And heal it did. August marked the release of "Paradise Valley," the crooner's triumphant return after a year away, followed immediately by a national tour.

And with that tour stopping Tuesday at Barclays Center we help get you ready with the essential Mayer tracks to add to your playlist before the show.

The hit single from 2001's "Room for Squares" put this pop superstar on the map. Combining a smooth blues sound with calculated pop sensibilities, this song snagged the singer's first Grammy Award for "Best Male Pop Vocal Performance." (Off "Room for Squares")

The songwriter's sophomore effort yielded him even more gold statuettes, this time for "Song of the Year" and "Best Male Pop Vocal Performance." It also cemented him as the go-to pop star with appearances on "Late Show With David Letterman." (Off "Heavier Things")

Further streamlining his blues background and contemporary pop sound, 2006's "Continuum" yielded even more hit singles than ever before and elevated his status among his peers to an elite level. Besides winning Grammy Awards for "Best Pop Vocal Album" and "Best Male Pop Vocal Performance," Mayer was also featured on the cover of Rolling Stone as one of the "New Guitar Gods."

The first single off his most recent effort features a duet with on again, off again girlfriend Katy Perry. Mayer has described the collaboration as completely professional in several radio and TV interviews. (Off "Paradise Valley")
