Music Critic/Hobbyist - Include in activities section?

I have 10 activities, and I wasn’t sure if I should delete one and replace it with this hobby:

Music Critic/ Hobbyist
May, 2016 - Present
15 hours/week
Total Hours: 300
Grades 11,12

Everyday for the past few months I've listened to 1-2 albums a day, after which I've rated (-/10) and logged. Many of these albums include classics, underground music, music dating back to the 60's, and new released music. I currently have 300+ rated & logged albums.

It’s a pure hobby but I think it’s something pretty unique and could very well be a good idea to replace one of my weaker activities with. Thoughts?

Do you write reviews? Because I don’t think anyone will be particularly impressed by clicking a number from 0-10 three hundred times.

(I knew a kid a few years ago who reviewed pop and indie records on a blog for years–his writing was phenomenal–who ended up at Harvard…)

@marvin100 I haven’t actually written out a review yet, but perhaps I could start?
