they have quite a few, what experience of creativity are you talking about? they have different songs, proper ones for each level, is it the sims 1 you have?
Hi. From what I can remember of the Sims 1, I know that one of the tunes (think it's like the second or third last level) is from Kinderscenen by Schumann. And either the top or the second top level they can play is Doctor Gradus Ad Parnassum by Debussy and the hardest piece is Flight of the Bumble Bee by Rimsky Korsakov. Hope this helps!!
the other piano songs are Rags by Scott Joplin. I know one of them is called the Pineapple Rag, the other is the Maple Leaf Rag. If you like Ragtime music, you could try The Entertainer, Solace, The Paragon Rag The Bethena Concert Waltz.
