Experimentation and new sounds alone cannot guarantee the success of an album. In that case each and every album released by ARR in the recent years should've been hits. Its ultimately the combination of films' success and variety which matters. To me GF has a certain edge over PP and VV as it has variety to its credit and also it's a typical commercial tamil film. VV and PP belong to the same category of films. VV sounds catchy, will be instant hit for sure, but it lacks variety, all the songs follow a similar pattern. PP songs gels with the theme of the film nicely. As of now its: 1) GF 2) PP 3) VV
