Why does one of the song sound so familiar?

Is it plants vs zombies 1 world 1 daytime song? :/

The music is made by Kevin MacLeod who made a lot of great songs and they are all free for usage so it's very likely that you've heard some of those songs in for example YouTube videos. :)

·3·) Oh, i see. My apologies, i mentally associated that song with PvZ.
Maybe I watched some video that had that song then. Or just a zombie game + familiar music ...
