He has released five solo studio albums: Out with a Bang (1994), Gettin' Out the Good Stuff (1996), We Can't All Be Angels (1997), Tryin' to Get There (2004), and No Zip Code (2018).
Murphy took a hiatus from recording in 2004, and has co-written several singles for other artists, including the hits "Living in Fast Forward" for Kenny Chesney, "Anywhere With You" for Jake Owen, "Big Green Tractor" for Jason Aldean, and "Are You Gonna Kiss Me or Not" for Thompson Square.
On April 6, 2018, Murphy and Kenny Chesney released a studio album together, No Zip Code, which features their hit song "Everything's Gonna Be Alright".
Trick Pony also entered the country Top 20 a year later with another one of Murphy's compositions — the title track to their 2002 album On a Mission.
The album, whose title track was co-written by Waylon Jennings prior to his death in 2002,[7] produced the Top Five hit "Loco", which reached #5 in 2004.
Following the closure of the Koch Nashville record label, Murphy continued working as a songwriter, scoring his first outside Number One with Kenny Chesney's 2006 single "Living in Fast Forward".
Other Murphy co-writes include Thompson Square's "Are You Gonna Kiss Me or Not" and "Everything I Shouldn't Be Thinking About", Kenny Chesney's "Live a Little", "Pirate Flag", and "Bar at the End of the World", Aldean's "The Only Way I Know", Jake Owen's "Anywhere with You", Blackberry Smoke's "Ain't Much Left of Me", and The Road Hammers' "Get On Down the Road".
