I read up on the way GRammy awards are given out.
any Recording Academy member (you must have been on a set # of recordings, or produced a set # of releases in a given time period to be eligible) can submit a list of songs/bands/albums for any respective category. This way, if you like Tejano and Classical music, you can nominate the acts you thought best for these respective genres. Everyone's votes are tabulated and then a top 15, based on total nominations, in each category is compiled. These ballots with 15 names/songs/albums per category are what are passed out to a specific set of "primo" Academy Members (the aforementioned super old, super rich, white dudes), allowing them to go hunt own a specific track or artist they may not have had a chance to listen to. These get voted on by them and then the top 5 in each category is voted upon by the Academy members at large.
This starts off well, even though it rides on lowest-common-denominator, but then is "filtered" if you will, through the musical mentalities of the "primo" old members, whose ears just cannot accept the genius of Future, or Young Thug, or the freaky electronic acts, etc.
