I really HATE when the right hand piano part is what she is singing. For example, that sheet music to White Houses how instead of the eigth notes it's what she sings. GRRR I hate it. I bought the White Houses book, though because I LOVE the cover art.
I also hated Paint It Black and Pretty Baby on BNN music book. You play what she sings! Sure I can understand Paint It Black but the chords sound much better for Pretty Baby!
I like Who's To Say and Annie on musicnotes. I think they release a new song each week. Hopefully, the Harmonium book will be out soon!
