A solo is just another part of the song, not the main event.
Clearly you don't listen to anything "soothing" because there's a lot of soft music around and implying it has no punch to it is like saying all soft classical music are all lullabies.

I listen to plenty of softer music, but those songs generally don't have guitar solos in them and so are irrelevant to this thread.
"Self-love", whatever that means, doesn't make sense.
All a solo is is an instrument adding some flair, whether it lasts a 8 measures or half a measure. It doesn't have to be a stand out part...
