Billie's Genes is probably the strongest piece, written from the perspective of Michael Jackson's love child (Billie Jean). It kicks off with a keyboard-synth horn riff, then the beat comes in. It's a clever turnaround on the original: the kid is fairly glad not to have grown up as Michael Jackson's kid. Aside from the MJ context, this song works. The arrangement is smooth with tight backing vocals.
Think Twice (It's Not Alright) is another strong number, with it's needy version of Bob Dylan. The harpsichord keys riff off the original melody. This is truly the anti-Dylan.
Think and then think againThe image of Dylan singing this one is hilarious.
Before you say it's too late for us
Think and then think again
I don't believe your mind is fully made up.
There are plenty of other great targets here: Avril Lavigne, Martha Reeves, the aforementioned Kanye West, and Frank Sinatra. Sit down with a pint of lager and have a laugh.
