Mariah Carey's new single "The Art of Letting Go" (Island) is straight-up crazy. Part "Vision of Love"-dramatic, part '60s-Motown catchy, it has no chorus, just kind of stream-of-consciousness anger that floats to a close, with wild lyrics like "Go to Mimi on your contacts, press delete."

This is what delayed her album's release for several months? What radio station format will play this? Compared to the focused, infectious "#Beautiful" single, "Letting Go" sounds like Mimi has lost her way.
