Play Music memory leak

I've been listening to Play Music for a couple days, and I found a disturbing fact; a memory leak. For every song I listen to, the size of the app data goes up a few MB and after a few songs it has skyrocketed to 150 MB. I don't know how to fix this, and my phone has only 1.27 GB of storage. Any help would be appreciated. [emoji26]
