It's probably better if you can get into the habit of reading notation...
I am currently learning "Suite In D Minor" by Robert DeVisee which is great, cos all the movements are different in style, feel and tempo, and each hold their own challenges, yet they are all attainable, so you don't feel like quitting... And cos it's Baroque, it's more fun to play, cos some of the livelier pieces jump around a bit more, but there's heaps of contrast with some really romantic style pieces as well...
