In my cloud drive settings (I have a temporarily-free-with-purchase 20GB account):

"Upload an unlimited number of songs in any supported file format with Amazon Cloud Player.

Supported file formats for songs Cloud Drive currently supports song files in the following formats:

.mp3—Standard non-DRM file format (Includes Amazon MP3 Store purchased files)

.m4a—AAC files (Includes iTunes store purchased files)

Any MP3 or AAC files added to your Cloud Drive will be available for playback and download using Amazon Cloud Player. Upload your music now with Amazon Cloud Player."

Do you know if this includes filters for length? For instance would rips of audiobooks be viewed as eligible for free storage?

> Files must be music recordings in MP3 (.mp3) or AAC (.m4a, iTunes non-DRM files) format and must be less than 100 MB in size... audio recordings that are not of songs and non-audio files (even if in MP3 or AAC format) are not eligible for unlimited music space.
