>But I felt guilty for not learning new things and just listening to music all day long

Seen this a lot, and I'm in the same boat. I dislike this commodified view of life and free time, where every thing you do must result in a sort of real-life stat increase, like you would see in a video game (Persona 5 anyone?).

I think ultimately this way of thinking is extremely naive. It implies there is no underlying themes or philosophy in music or fiction whereas listening to a podcast will cause you to learn something new. The subtle messaging a good album possesses can be far more profound than listening to a guy talk about data science for an hour each day. Listening to a good album or reading fiction can give you new ways to frame problems or reconsider old approaches in your work.

We need more polymaths.
