I've been trying to expand my musical taste lately. So I found a recommendation for "Kalk Samen Kuri no Hana" by Sheena Ringo. I listen to it on youtube and it sounds awful, even though all the comments praised it. Maybe it's just not my thing...
Then I listened to it in my car, where I had an actual subwoofer. So I found out that the sub is literally required to listen to the album. It's good.
