Hi,

I'd try classical: Mahler, Brahms, Schubert, Mendelssohn, Vivaldi, Bach, Tchaikovsky, Debussy, Bizet, Dvorak, Chopin, Fauré, Litz, Couperin, Berlioz, Albéniz ...
You have songs within these composers that will make any kids think twice about Classical Music ...

Where do you think that bands like Scorpion, Queen ... had pulled their hits from?
