A couple of piano played songs. I actually play the piano myself, and listening to these songs is what keeps me motivated.
Very high in my list of my favourite piano pieces is the one from The Piano. Good film but very sad film. It did have a happy ending though... so that equals a happy me haha. (I'm still really annoyed at whoever decided on that HORRIBLE ending for the film Atonement. Shame.)
Another song is Nuvole Bianche by Ludovico Einaudi. Love this composer. His pieces are quite simple really, but played well they can be really expressive and that's something I 'get'.
