It's a great dance / electro song with a good rhythm. Of course you should like music of this kind, but then one of these song even inspire. For pop charts and listeners, it is perhaps to electric? I do not know much of Timberlake and have short time here on Amazon in "Justified" reingehört, and that is different. So a Timberlake fan should perhaps listen earlier times.
I refer also to the other reviews here on Amazon with a different version of SexyBack.
