There are two very common brands that carry MP3 players with built in FM radio, Coby and Sandisk (Sansa). http://www.walmart.com/ip/Coby-4GB-Micro-FM-Radio-MP3-Player/14312687 http://sandisk.com/products/sansa-music-and-video-players/sandisk-sansa-fuze
Whether or not an MP3 player has am/fm settings depends on the brand of the player. Some brands, such as Coby, SanDisk, Zune, and Sony have fm settings but don't have am settings. Other brands like CCWitness have both am and fm settings. Apple Ipods do not have a either fm or am settings. http://www.amazon.com/s/ref=nb_sb_ss_i_1_22?url=search-alias%3Delectronics&field-keywords=mp3+player+am+fm+radio&sprefix=mp3+player+am+fm+radio#/ref=nb_sb_noss?url=search-alias%3Delectronics&field-keywords=mp3+player+am+radio&rh=n%3A172282%2Ck%3Amp3+player+am+radio
