A full hour of streaming music can use upwards of 150 MB of data. That means a single hour of streaming per day can add up to over 6 GB of data usage just for streaming music.

Streaming Hours to Reach 1 GB: 92.5 hours

Streaming Hours to Reach 1 GB: 23.1 hours

Streaming Hours to Reach 1 GB: 13.8 hours

Streaming Hours to Reach 1 GB: 6.9 hours

In terms of data usage, 320 Kbps translates to approximately 2.40MB per minute of audio or 144MB per hour. So, streaming music for an entire 8-hour workday would chew through over 1GB of data.

Pandora Free: Wi-Fi streams music at 128 kpbs and will use approximately 58MB per hour.

Pandora Free: Mobile data streams music at 64 kpbs automatically and will use roughly 29MB per hour.

Pandora Plus or Premium: Wi-Fi or mobile data uses 192 Kbps automatically and will use approximately 86MB per hour.

Low (free & premium): Streams music at 24 kbps and will use approximately 11MB per hour.

Normal (free & premium): Streams music at 96 kbps and will use approximately 43MB per hour.

High (free & premium): Streams music at 160 kbps and will use approximately 72MB per hour

Very high (premium only): Streams music at 320 kbps and will use approximately 144MB per hou

HD: About 383MB per hour.

Super HD: About 1.68GB per hour.

Amazon says that its average bitrate for HD (lossless) files is 850kbps, and the average bitrate for Super HD is 3,730kbps.

256 kbps no matter how you listen, meaning you'd use approximately 115MB per hour.

It takes about 500 KB of data to stream one minute of music and there are 1 million KB in 1GB. So if you do the math (or if we do), that means you can stream approximately 33 hrs and 20 min of music with 1GB of data.
