Thanks for posting this, @Mario - I didn't think I had much to say on this, but apparently I underestimated myself 😛
As with most music which truly inspires, it's hard to pin-point what it is about a particular song which makes you feel a certain way, let alone inspire you to change for the better: I think inspiration - at least for me - tends to bypass the brain and goes straight for the heart. And while it might not express itself in a concrete resolution to strive for better, when at its best, music can soundtrack important moments in your life in a way which makes you feel understood and thus lightens the burden of whatever you might be carrying in those moments.
To go back to the question - while I'm not able to pick out any one song in particular, I can identify a characteristic shared among a group of songwriters who I'm listening to which I admire and which I'd like to emulate. Broadly put, this is the ability to serve others through one's work. Contemporary pop songwriters are becoming increasingly open about themselves in their music, even to the point of brutal sincerity. This way of sharing which bares all and spares no details seems to resonate especially with younger generations. Examples of such artists include Lauv, Maggie Rogers, Alec Benjamin, Billie Eilish, Rex Orange County, Sasha Sloan, Chelsea Cutler, The 1975, to name but a few.
I have at times been skeptical and wondered whether all this is done in the name of appealing to the mass market of the 'broken' youth. However, similarly to how people take what one reads in someone's autobiography as being true (at least as far as the author is concerned), I believe that songwriters who choose to open up to their audience through their music also deserve the same treatment: that is, that we accept that what is written on the page and subsequently performed in front of crowds comes from a genuine place. We should also allow for the fact that, at the end of the day, music is an artistic medium, and as such has to be flexible to accommodate for any deviation from the truth that it is attempting to convey.
I've personally gone from adulating said songwriters to ridiculing and rejecting them altogether. However, having experienced both extremes, I've more-or-less settled for a more measured middle-way and accepted their music for what it is: a wildly subjective, often naive and severely misguided, but ultimately sincere attempt at a snapshot of one's (troubled/frail) state of mind which represent a significant moment or period of one's life. And, going back to the initial premise that this is ultimately of service to its audience, I can attest to its ability to positively influence and, in the process, I've had to check myself and learn to accept a priori that people's intentions are fundamentally good.
To redeem myself for an unduly long response to a seemingly simple question, here's a track whose title encapsulates the nature of such songs.

I do happen to also have an entire playlist with songs from all the artists who I believe represent this movement of bleeding-heart-on-sleeve songwriting. As the name suggests, it's dark, but hopefully it gives people a better idea of what I'm banging on about:
