The best songs, the ones that get accolades, the ones that get played over and over again, the ones that get played 50 years after the first time it was played; those songs are almost always about love. Yearning, mourning, celebrating, love. Between fathers and sons, mothers and daughters, husbands and wives, girlfriends and boyfriends, partners who have passed.
The Beatles told the world that all you need is love in 1967. Roxette sang in 1989 about how it must have been love, but they lost it somehow. Also the same year, Richard Marx sang about how it breaks his heart to oceans apart from the one he loves, but was still right there waiting. Aerosmith put into song what a wonderful feeling it is to not want to fall asleep for fear you'd lose a single moment with the person you love in 1998. 3 Doors Down mourned a long distance relationship with Here Without You. James Blunt asked his lover if he disappointed her as he bid her goodbye in song in 2005. More recently, Adele sings about finding someone like her former lover, and reminiscing about what they once together.
Nine out of ten songs played on the radio is about love. It's no surprise, course, because at the end of the day, all you want to do is be loved. Whether it's from your parents, from your friends, from your partner. I think love is the ultimate selfless emotion a human being can experience. It's all-consuming, it's intoxicating, it hurts, it disappoints, it's exhausting, it's addictive. It's everything you've read about, and listened to, and yet, on the whole other spectrum, it's not. It's secretly paying your dad's parking fine just cos', it's taking your mum out for brunch because you feel like it, it's texting a friend about how proud you are of her, it's telling someone that you love him and not expecting anything in return.
It's just the best thing ever. :o)
