Param,
It's a delight if you like WCM orchestra sounds. I'm one and that's my main reason for loving this album, more than anything else.
If you go exclusively by vocals (I know your love for SPB), you should not have too much expectations. You'll still love the two female solo songs 'saRRu munbu' & 'mudhal muRai pArtha gnAbagam' but I can't assure you if you'll thorougly enjoy the rest.
With that mindset, if you listen to the album, you're in for a treat :-)
