No doubt, it will be the summer song. It's a very special version of a song called Rapper's delight, and the words try to be a fonetic aproximation to the English ones.
I have already learnt it :
Aserejé ja dejé dejeve tude jébere sebiunouva majavi tude bugui ande vinidipí...
The original one said:
I have an n on an n ....... or something like that.
THIS year foreigners have easier than Spniards to learn the song of the summer
