Pop music often searches to find the eternal in the everyday. Songs attempt to freeze time around one emotional moment - I haven't got enough money! I wish I could wish on a falling star! Girls are sexy! - and to make sure it's communicated to as many people as possible,it'll often take place in the most mundane of locations:a street,the house you grew up in,a nightclub.
It's partly because gems often shine brighter when placed against a dull background,and partly a way to bring extra reality to the situation,so it feels truer. In the same way that we all tend to sit up and take a bit more notice of a film that says that it is based on a true story.
This is why it's a good idea to write a song with a bike in it. It's not just a fun hook to hang a lyric from,it speaks to our inner child. Most of us have ridden a bike,right? Well this sings to the part of us that yearns for a simpler life,free of boring distractions.
In fact (drumroll) it's not just a pop song,it's an integral part of the cycle of life (TISH!).
