The music book Sounds Good On Accordion contains a wide, genre-spanning selection of light to medium-heavy songs, which are perfectly suited for the accordion due to the melody and a not too complex rhythm.
Title selection: Lemon Tree (Fools Garden), Don't Worry, Be Happy (Bobby McFerrin), Chan Chan from Buena Vista Social Club, Le Moulin from the movie The Fabulous World of Amélie, No Roots (Alice Merton), Be Mine (Ofenbach), Wrecking Ball (Miley Cyrus), Your Song (Ellie Goulding) or Something Just Like This (The Chainsmokers & Coldplay).
