I prefer color pop balloon because it helps a lot by itself, but also gets you the other booster that is in the game very fast if not instantly as well.
One of the best songs party song for me is : Kaoma - Lambada. Such a lovely, romantic and beautiful song and music as well. Very close is Bandido from Azucar Moreno. This song makes me feel good and up for dancing all night. Or Shakira Ojos Asi. This song is perfect for mood setting. Can't post videos, sorry. Cheers!!!
Disregard my previous answer. It was only guessing. Now I tried really hard to count hearts, and I counted somewhere between 115-120. My answer would be 115.
