App, these were songs which IR sung track for I believe, and realsing those on the cassette was for satisfying his hard core fans, some of whom believe his naanaga naan illai trumps SPB's version. Sugar content on SPB's voice being high, some diabetics need Raja's insulin to counter-balance the sugar in the album when SPB features in the album :-)
