I think that the songs you have choosen are just fine. I really like the Adam Sandler song. It’s very cute!

Since you like Adam Sandler, check out the soundtrack from 50 First Dates. Not sure if nay of his tracks are on there, but it is good beachy love music, and not just the typical wedding songs (the remake of Somewhere Over the Rainbow is GREAT - not sure who does it)
