Ok, I'll bite. Of course, I have gazillions of faves from all genres and eras of music, but the one that always stands out to me is James Honeyman Scott's solo on The Pretender's "Kid." To me, it's the perfectly brief, tasteful, and musical pop solo that's so well-suited to the song. :nevreness:
Ah, "tasteful and brief and well-suited to the song" - George Harrison's solo on "Something".
And many other Harrison solos...
