America's Best Music

America's Best Music is the on-air branding of an adult standards 24-hour radio network, known internally as Adult Standards and formerly known as AM Only. The service is syndicated by Westwood One, a subsidiary of Cumulus Media. It was one of the original Transtar Radio Networks formats. "America's Best Music" is no longer exclusive to AM stations and is carried on some FM stations.

Its main competitor is Music of Your Life, syndicated by Planet Halo, Inc. Until 2010, Timeless from Citadel/ABC Radio had been another similar format.

The target audience of the format is persons 35 to 64, with 40 percent of music from the 1960s, 30 percent from the 1970s, and 15 percent each from the 1950s and since 1980. Artists include Neil Diamond, Frank Sinatra, Barbra Streisand, Tony Bennett, The Carpenters, Johnny Mathis, Barry Manilow, Celine Dion, James Taylor, Elton John, Anne Murray, Andy Williams, Engelbert Humperdinck, Linda Ronstadt, Nat King Cole, Captain and Tennille, and Simon and Garfunkel. The format also incorporates "new standards" material by artists like Norah Jones, Diana Krall, Michael Bublé, Steve Tyrell, Rod Stewart, Bette Midler, Carly Simon, and Renee Olstead. Also, the network plays continuous Christmas music beginning in mid-December through Christmas Day each year.
