Planetary by Bloom

“An all-new, stunningly beautiful way to explore your music collection.
Available only on iPad.”

Artists are Stars:

Every star in Planetary represents an artist from your music library.

Albums are Planets:

They orbit around their artist star. The planet surface is derived from the album cover art. No two planets are the same.

Tracks are Moons:

They orbit at a speed based on the length of the track. The size of the moon is based on the play count.

Filter Artists by Letter

Create a constellation of highlighted stars by filtering artist names by their first character.
