Actually in LOVE with whoever made this

The video likely resonated due to the relatable expression of admiration for a talented musician and the intriguing display of a novel music transcription app. The "surprise" reaction and the visual appeal of the app's interface likely captured viewer attention.

The video shows a person reacting with surprise and delight to a piano performance being played on a phone. The phone screen displays a TikTok video of a man playing the piano, with the caption "Actually in LOVE with whoever made this". The user then interacts with the phone, seemingly to save or share the video, and the app displays a "Convert to Waterfall" option, suggesting it's a music transcription or practice tool.
