This beat is making me see things that I didn't think I could see...

This is the first Audio challenge I've done! Exciting! The challenge name immediately brought me to the idea of checking out the waveform/spectogram of the linked MP3 file. I've used Audacity in the past for old university music programming assignments, so I went there first and looked at the waveform and spectogram. I couldn't see anything here, so I went to Google to do some digging. I came across a John Hammond video on Audio Spectograms. He mentioned using Sonic Visualizer for these type of challenges so I installed it and opened the MP3 file there.
I could see some Hex straight away, so I manually typed them out into a Hex -> ASCII converter and got the flag.
