Frankly, this one is for hard-core McCartney fans only.  I've been a total Beatle fanatic since their earth-shattering TV appearance in '64, but every historian or knowledgeable musician will tell you that the 'magic' music recipe they possessed was indescribable; so powerful that to this day the Beatles are THE example by which all others are measured.  But when they became solo artists everything changed.  They produced a few unforgettable songs and albums, but all told, they had become 'part of the crowd'.  One of the best examples of this was Wings At The Speed Of Sound.  If I didn't know this was McCartney I would have described it as "...fluffy drivel".  Considering that the best track is "Silly Love Songs", which is precisely what it is, tells the whole story.  Plodding through a painfully superficial album of 'product' music was hard enough, but after "Cook of the House" it was time to stop eating the candy and reach for some steak.  McCartney addicts consider anything he does a must-have, but for casual listeners there is far, far better elsewhere in the McCartney catalog.
