Over the years, popular music has found ways to document the challenges surrounding mental health. While many of these songs are moving in their unflinching portrayal of depression, there is an equally sizeable body of work tackling the subject matter with a lighter touch. While it's easy to dismiss these often peppy ditties as too lightweight, they can be effective in lifting the mood, even for a few minutes, in these fraught times. Here are ten eclectic songs that remind us to look at the brighter side of life.

In tailoring the message to a younger, digitally savvy audience, the song focuses on the destructive effect of words in this era of cyber bullying. How to overcome the hate? Pay it no mind and "you are bullet proof". Taylor Swift may have written the song in response to the "hate, hate, hate" that comes from being a pop star, but the brilliantly conversational lyrics and exuberant pop production allowed the song's message of self-empowerment to hit home, and in turn, the top of the charts. Inspired by a pun regarding Destiny's Child's revolving door of members, the trio crafted a bullish and confident message to their detractors with this 2001 hit. It is a now a favourite of gym classes worldwide. We all asked ourselves the question at some point: is who we are or what we are doing relevant?

Casting his career as a relationship on the rocks, he declares: "I'm still standing after all this time. Picking up the pieces of my life without you on my mind.” For his classic album <em>Thriller</em>, Michael Jackson was looking for a rock song to provide balance to the pop tracks he'd already recorded. To suit the tough guitar riffs, his lyrics focused on the scrounge of gang violence afflicting the US at the time. The message here is that true strength is found by conquering your own demons and not by lashing out at the world. The Palestinian-American producer is the hip-hop version of motivational guru Tony Robbins.

A major hallmark of the English group's output is singer Sade Adu's enigmatic vocals and word play. This is one of the rare occasions when she lets her guard down and embraces the joy of living in the moment.
