Also, I love songs that have a pleasant connotation for me, even if it is a silly one. Someone posted a popular cover of Elvis's "Can't Help Falling in Love." I recognized the song although I did not know from where and hadn't known it was an Elvis song, what the title was, or anything. When I looked up more covers, the ad on one cover video ended up being the very place I had first heard the song.
I just love the ad; it is so cute and the song is so perfect for it.
