Nashville sound? Nashville songwriter's viral mashup shows why country music all starts to sound alike after a couple of minutes

Ever wonder why the songs on your favorite country music station all sound the same after a while? Nashville songwriter-producer Gregory Todd says his mashup "was made 'all in good fun,' not as a way to bash the music or the artists who are dominating the radio," according to an article in yesterday's Nashville Tennessean. Well, OK, sure. But it certainly does show what happens when songwriters and record producers have to hew to a formula in order to get airplay.

The songs are:

• Blake Shelton's "Sure Be Cool If You Did"
• Luke Bryan's "Drunk on You,"
• Chase Rice's "Ready, Set, Roll,"
• Parmalee's "Close Your Eyes,"
• Cole Swindell's "Chillin' It"
• And "This Is How We Roll," recorded by Florida Georgia Line.

Todd, whose YouTube user name is "Sir Mashalot," says his next project is "a new musical experiment: a song specifically written to fit his mashup formula." OK, sure. I don't know how new that is -- seems like that's what they all do -- but I'll bet it gets some airplay.
