this makes no real sense since idk if its about release date or what i believe was nice at the time
and limiting it as well is pretty damn weird
i googled the 2011 song and it was released in 2009 so im going w my opinion by the years
2009 - Crazy Frog - Axel F
2010 - Thomas The Tank Engine Theme Song
2011 - Орк. Никая - Баща Ми Е Кондуктор
2012 - PSY - GANGNAM STYLE
2013 - MACINTOSH PLUS - リサフランク420 - 現代のコンピュー
2014 - Vicetone & Tony Igy - Astronomia
2015 - Basshunter - DotA
2016 - Smash Mouth - All star
2017 - Luis Fonsi - Despacito
2018 - Plazma Burst 2 - FAN MADE RAP - Eru
2019 - Shadilay - PEPE
2020 - Song for Denise (Maxi Version) - Piano Fantasia
but fr tho since im very funny
but fr this is rly hard so ill go by what i kind of know
2010-2013 i was into like normal rock n stuff, mostly grunge, heart shaped box by nirvana, rape me by nirvana, a lot of stuff like that i greatly liked
2014 i got more into metal so like peace sells by megadeth
2015 i dont rly know as well but probably vaporwave fr, floral shoppe is great in its entirity but i go with the 1st track called boot - the 1st one in the album aka ブート - over the one i mention in the list, that one is rly unique and vaporwave is rly deliciously exquisite pizza sauce nice after all
2016 - prob the year i got introduced to synthwave so prob HOME-resonance or something within the lines of that
2017 - i got into shred metal, jason becker - altitudes kind of is the best out of that imo but at the time i prob would pick black star by yngwie malmsteen
2018 - deeper into classical music, probably dvorak's 9th symphony, 2nd and 4th movements the most
2019 - deeper into classical music, baroque n bach fanboy times tho so the BWV 582 passacaglia n fugue in c minor
2020 - also deeper into that but i instead pick the ricercar a 6 from the musical offering aka the BWV 1079
