I use to listen this song in the corridors of my university. And I keep thinking where does it come from. There are no lyrics, just a (hesitant) piano that interprets a song that should come from a film/series. None of my friends could identify it. But it rings a bell to me!
One good friend of mine does have a prodigious memory an after two tries he came out with a video.
I was amazed. Indeed, it is Joe Hisaishi - Summer. Very appropriate title for the wonderful experience I'm having abroad this summer.
It would be wonderful if google let search songs in its engine but I think this is currently impossible right?
