"Kotoba ni Dekinai" (言葉にできない Kotoba ni Dekinai?) is a Japanese song sung by Off Course in the background of the TV series Sonic X. It was featured in the broadcast version of the twenty-sixth episode "Countdown to Chaos" during the scene where Chris grabs the Chaos Emeralds. It hasn't been included in other versions like the DVD releases due to copyright issues
