Hello InTrees,
Thank you for reaching out in Apple Support Communities. We understand you're unable to download two songs from the iTunes Store on an iPhone.
Managing your purchased music is important, and we'd like to help.
We recommend to try on both cellular data and Wi-Fi to see if you can download your music from the iTunes Store. This can help determine if this issue is isolated towards an issue with the network connection.
In addition, you want to ensure there's enough available storage space to download your music on the iPhone. We'd like to share with you this article about the difference between iCloud storage and device storage: What's the difference between device storage and iCloud storage? For the proper steps to determine if there's enough available storage space on your iPhone, please follow the section that says, "Device storage."
Also, you want to ensure that your iPhone is updated to the latest version of iOS 14.0.1. This provides software improvements that can help: Update your iPhone, iPad, or iPod touch
We look forward to hearing an update on the results.
Kind regards.
