Only time will tell what effect Camila Cabello’s exit from Fifth Harmony will have on the group’s future. What Genius does know, by crunching numbers, is what impact Camila has had on 5H’s existing music.

As a quintet, Fifth Harmony released two studio albums, Reflection and 7/27, both of which peaked in the top five on the Billboard 200 chart. The latter album featured their hit single “Work From Home,” which is the most-viewed music video on YouTube in 2016 with 1.2 billion views.

Statistically, Camila contributed heavily to both albums. Based on the numbers, below, some fans might say she’s carrying the team, while others might say this shows an unfair distribution of solos and harmonies.

To calculate the percentages, Genius counted the number of lines of lyrics in the 26 songs from Fifth Harmony’s two U.S. deluxe edition studio albums. Then we tallied how many lines each member sang—including solos, shared choruses, shared verses and shared bridges—meaning numbers won’t add up to 100% because of harmonies.

Debut Album: Reflection

Total lines of lyrics: 673

1. Camila: 347 lines (51.6%)

2. Normani: 290 lines (43.1%)

3. Ally: 266 lines (39.5%)

4. Dinah: 250 lines (37.2%)

5. Lauren: 229 lines (34%)

Sophomore Album: 7/27

Total lines of lyrics: 604

1. Camila: 224 lines (37.1%)

2. Lauren: 173 lines (28.6%)

3. Dinah: 153 lines (25.3%)

4. Normani: 133 lines (22%)

5. Ally: 124 lines (20.5%)

Both Albums: Reflection and 7/27

Total lines of lyrics: 1,277

1. Camila: 571 lines (44.7%)

2. Normani: 423 lines (33.1%)

3. Dinah: 403 lines (31.6%)

4. Lauren: 402 lines (31.5%)

5. Ally: 390 lines (30.5%)

Camila’s full-fledged venture into solo territory (5H announced she “quit” the group on Dec. 19) isn’t so surprising when you look at the numbers. These statistics show Camila played a major role in Fifth Harmony’s sound. Harmonizers on social media have pointed out this unbalanced distribution before, but now there are numbers to support their tweets.

Of the 26 songs analyzed, 11 of them have Camila contributing the most lines or tied for contributing the most lines. Some observers on Genius even labeled Fifth Harmony’s song “The Life” as “The Camila Song” because of how much Camila dominates.

Here’s a montage of Camila’s solos from the albums, covers and more:

The numbers, of course, only reflect how much each member gets to sing, not who’s the strongest vocalist. Let’s not forgot that all five girls were discovered after they auditioned separately on The X Factor USA in 2012. The judges were impressed by each of them before assembling them into a group, which placed third that season.

Camila has already found relative success branching out from Fifth Harmony this year. Her “Bad Things” duet with Machine Gun Kelly rose to No. 10 on the Billboard Hot 100 this month.

And Camila’s “I Know What You Did Last Summer” duet with Shawn Mendes peaked at No. 20 in January.

Meanwhile, some people are already even imagining how Fifth Harmony will sound without Camila. One YouTube user posted this “Fourth Harmony” version of “That’s My Girl” sans Camila’s vocals.

Camila isn’t the only one working on solo projects. Lauren Jauregui collaborated with Marian Hill to release “Back To Me” this month. And Normani Kordei unleashed a cover of Drake’s “Fake Love” and “Sneakin.”

Lauren, Normani, Ally Brooke and Dinah Jane have promised fans that they “will continue with Fifth Harmony as well as [their] solo endeavors.”
