The deep bellowing is now being attributed to the recently discovered "extra pair of vocal folds" outside the koala's larynx. These folds are "over three times longer and around 700 times heavier than the laryngeal vocal folds".
What Spotify Pays Out
Spotify recently released a report on how it pays its labels and artists, and it isn't per stream. If you think listening to your favorite indie artists on spotify helps support them, consider this: all the money gets thrown into a pool, most of which gets distributed out to the most popular streams.
Spotify keeps 30 percent for itself, and 70 percent goes to the "master and publishing owners." So if the music is owned by a label, the 70 percent goes there; if the music is owned by the artist, the payout goes directly to the artist. The 70 percent figure appears to be a bit flexible.
Musical training has the ability to change the shape of your brain (for the better) and the functions of its regions, according to these researchers, who found it improves the plasticity of the brain and is helpful in treating various disabilities:
Long-term high level musical training has a broader impact than previously thought. Researchers found that musicians have an enhanced ability to integrate sensory information from hearing, touch, and sight.
The age at which musical training begins affects brain anatomy as an adult; beginning training before the age of seven has the greatest impact.
