# Rick Roll Do Not Listen (Grab Bag 100)
We're given an audio file of Rick Astley's "Never Gonna Give You Up".
I've gotta admit that I struggled on this longer than I should have. I tried doing spectrum analysis, frequency analysis, binwalking, etc.. No dice.
Turns out, the secret data is embedded as audio samples inside of the audio file. This is a common steganography technique with audio files, since image and audio steganography differ greatly.
We can use steghide to pull the embedded data outside of the audio sample.
```$ steghide extract -sf RR.wav...MCA{asFSA9123mflZ01f}```
