Over the years the winners of Grammy awards have ranged from the has-beens (Steely Dan) to the drama queens (Madonna).
But if the music industry's equivalent of the Oscar awards on Sunday night fails to honour two men by the names of Danger Mouse and Cee-Lo with a prize for record of the year, then you know that the whimsical musicians who choose the winners should probably check into drug or alcohol rehab.
Here is a little help if the names Danger Mouse and Cee Lo do not ring a bell.
They are the pair behind the break-out duo Gnarls Barkley and the hit that you have no doubt hummed to yourself numerous times throughout the past year: that infectious, adventurous, funky pop hit Crazy.
Still that is no guarantee of success as the dynamic duo - who often dress up as Star Wars characters for their live shows - are going up against eight-time nominee Mary J Blige, and the new liberal political darlings The Dixie Chicks, not to mention such perennial favourites as Justin Timberlake, the Red Hot Chilli Peppers and John Mayer.
Some are guaranteed to go home with a prize Sunday night. Legendary rock bands The Doors, The Grateful Dead and Booker T and the MGs are to receive lifetime achievement awards along with the late opera singer Maria Callas, folk singer Joan Baez, jazz saxophone player Ornette Coleman and late country music icon Bob Wills.
The tributes add to the sense that the Grammys are the biggest night of the year for the world's recording industry, when most of the big players mingle on the red carpet and in numerous after-parties.
The Grammys are also by far the best of the entertainment industry award shows, thanks to the habit of giving out all but the biggest prizes off camera, and devoting the precious air time to one-off appearances that feature great artists in unique collaborations.
This year's line-up is led by the iconic 1980's rock band The Police, who split up in 1984 after garnering five Grammys with such rock classics as Roxanne, Message in a Bottle and Every Breath You Take.
Though the three-man band is not officially reuniting, they are expected to announce a US and Britain tour to mark the 30th anniversary of the release of their signature hit Roxanne.
Other great Grammy moments should be provided by international singing sensation Shakira, who will perform with Haitian hip-hop master Wyclef Jean.
In addition to this, all the best song and performer nominees will take the stage and there will be two tributes to James Brown.
This emphasis on showcasing the best pop talent in the world, rather than just giving them statuettes, is what has enabled the Grammys in recent years to finally shrug off its unwelcome moniker of The Grannys.
It has also led the Washington Post's influential music critic Eugene Robinson to see the show as offering "a better, more finely detailed portrait of the American zeitgeist than either the Oscars or the Emmys".
