Only the 5G and 6G iPod can go beyond iOS 6 and the 6G original came with iOS 8.

The 5G and 6G have 5 rows of apps and the dock row.

If yo do not have a 5G iPod then yo maybe able to get the latest version compatible with your iPod

Starting when iOS 7 was released, Apple now allows downloading the last compatible version of some apps (iOS 4.2.1 and later only)

You first have to download the non-compatible version on your computer. Then when you try to purchase the version on your iPod you will be offered a compatible version if one exists.
