Here are two options for the easiest songs to get 100 percent on, one on-disc and one DLC/import song. Rock Band 3 actually allows you to play a song in multi-player, even if it doesn't have the part you are playing. I do not know if the game will award you the achievement if you have no notes, though.
Drums: Nine in the Afternoon by Panic! At the Disco, Polly by Nirvana (DLC). Polly's drum part consists of 4 Yellow/Blue hits. 8 notes total. Nine in the Afternoon is more involved.
Bass: Eye of the Tiger by Survivor, or Roxanne by the Police (DLC).
Guitar: Eye of the Tiger by Survivor, or The Jack by AC/DC (AC/DC Live pack).
Vocals: Sabotage by Beastie Boys, or Laid To Rest by Lamb of God (DLC). These songs are all "talky" parts, therefore you are not graded on pitch, you could even have something generate a steady tone for the duration of the song, and have it loud enough for the microphone to pick it up, if you're desperate.
The song "Charlene" by Steven Colbart is extremely easy and is great to get the 100% on an expert song trophy. The only thing is that you have to download it from the online store; but it's free!
