What will happen if the price of CD players decreases the demand curve for compact discs slopes downwards, and the supply curve slopes upwards(in the graph below)?

I thought a change in own price will only affect the quantity demanded and not demand. Is my thinking worng or incomplete?

The equilibrium price of compact discs will rise

Clearly CD players are a complementary good to compact discs. So if the price of CD players decreases the demand for them will rise and so too will the demand for compact discs. Hence the demamd curve for discs will shift to the right causing the equilibrium price to rise.
