Early 2010's vs. mid-2010's

Definitely the early 2010s. They were repetitive and formulaic, but nonetheless lively, melodious, spunky, and carefree. 2014 was a decent year for music, but 2015 and especially 2016 were dull, miserable times for music. So far, the late 2010s are proving a remarkable step up from the wretchedness of the mid-2010s.

I'm voting Mid 2010s.

For one, my personal life, the early 2010s were an absolute low point for me, the mid 2010s on the other hand were a high point.
Middle school (2009-2012) was horrendous, worst years of my life by far. But then freshman year came, and it was a major improvement for my personal life. Then came sophomore year, which was hands down the best school year of my life, a total polar opposite to where my life was only a couple years prior. Junior year was fun, but it's also a pretty infamous year for me, by then my ego was getting out of control, I started flirting with every girl, arguing with my friends and treating them badly, getting on the nerves of the teachers I'd normally get along well with, I thought I was Jesus Christ, and it tainted and almost ended a few friendships of mine. Senior year was also fun, though pretty quiet for me since a lot of my friends had graduated and I wasn't there full day anymore.

For two, it was in the mid '10s when Adam Gontier, the former vocalist of Three Days Grace, got back in a band, called Saint Asonia.
Also, it was in the mid '10s when Alestorm released "Sunset on the Golden Age", aka their best album of all time in my opinion;

Voting mid-2010s, as it is when my interest in music peaked since the late 2000s, the first year of my music resurgence being 2013.
