Great 'unpopular' works of popular music artists

[I. Spaceman]

I'm Leavin' is excellent and deserved a better commercial fate. I like Always On My Mind a bit more, tho.

McCartney II is experimental, as was the first album, that's why it was dubbed a sequel. I love both. His modern equivalents are the Fireman albums, which I think are far better than the vaunted albums he has put out under his own name in the same era. But, I like weird Paul the best.

The only McCartney I like is when he's not being "Paul McCartney, ex-Beatle" which he is (unsurprisingly since it's obviously phenomenally profitable and whatever) 99% of the time. That is why McCartney II rules.
