Song-writing can be challenging sometimes, but here’s how you can make it that slightest bit easier:
If you have an idea, record it!
One of the most annoying things I’ve found when song-writing is when an idea pops into your head and you haven’t written it down or recorded it, and then you’ve forgotten it. Even if you might not believe it’s “the best” idea, there is opportunity to tweak it into something better or something new. I’ve come to writing on my hands, arms and legs when I’ve thought up an idea, I’d recommend paper only because pen can take it’s time washing off and it’s probably not the most ideal for your skin – so maybe carry around a little notebook you can jot ideas down into if you need.
Don’t force it
If you’re struggling to come up with anything, the best thing you can do is leave it for a while and come back to it later whether that’s a couple hours or days; forced lyrics tend to be generic and will, more often than not, sound forced.
Sometimes I find it helps to play a few chords or notes over and over and to sing lyrics as they come into my head. It is likely that most of what you come up with will be discarded but you'll almost certainly come up with something that you can use whether it be lyrics or melody. Make sure to record this so you can come back to it at a later point.
people usually listen to songs which they can relate to, but also that you can relate to. The best songs are usually the ones that come through experience because the emotion delivered is real and genuine and thus makes the song more believable.
Just listening to everyday conversations can evoke inspiration. A lot of songs have phrases that are used from day to day speech for instance: "you need to calm down" (Taylor Swift). Sometimes listening to phrases and speech used by the people around you can help to trigger lyrical ideas of your own.
