Adele - Someone Like You gets me every single time. It's just one of them songs I think anyone who has been in love can relate to and really pulls at the heart strings.
Here is the list of my favorite three songs that can made my tear up.... Show Me The Meaning (West Life) Every Night In My Dreams (Jenifer Lopez) Mr Lonely (Akon)
Vaana (tamil language movie) is the movie (failure love story) which made me to cry. Awesome movie with story line.
