Line distributions in K-Pop songs can be a tricky subject. While some members in groups are stronger with vocals and others are stronger in dance, sometimes the amount of time each member has to sing in a song can vary widely. It makes sense that the “power vocals” of a group would have more lines, but when the line distribution becomes too uneven, it can upset fans, and make people wonder if there is bias in a company.

Here are 14 different girl groups, comparing their best-distributed songs to their worst-distributed songs. It’s interesting to see the differences between each – but good to know that not all songs for any one group show an uneven amount of distribution.
