This document will probably help you http://www.advancedcustomfields.com/resources/querying-relationship-fields/

Chackbox fields are stored as arrays similar to the way relationship fields are stored.

So your meta query would look something like this.

meta_query' => array(
  array(
    'key' => 'music-taste', // name of custom field
    'value' => '"' . $taste . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
    'compare' => 'LIKE'
  )
)
