I think it's "Paboritong"
Anyway, the maps that changed my entire osu! life are probably my favorites
http://osu.ppy.sh/s/1652 -- Akitomo Takaya (...supposed to be Akina Takaya) - Battle Frontier. The song I have never FC'd even until today. The Insane of this map was the map that trained me on z/x (now ctrl/alt), and grinding my teeth until I frustrate myself to death. 2319 plays for now. Even today this is my most favorite map, despite the horribad timing. I garnered those 2000+ plays even before I played
http://osu.ppy.sh/b/1147 -- IOSYS - Marisa wa Taihen na Mono wo Nusunde Ikimashita. If the 3000+ plays doesn't give out that clue then I don't know what. I played this mainly because I liked grinding for accuracy. But this wasn't the map that trained my beatsense, as my beatsense was already awake due to playing the Taiko games. This was just an attempt to hopefully say something for myself, and thus sprung about the race for #1 between ShaggoN and me... before Cookiezi came, that is.
http://osu.ppy.sh/b/24482 -- Pokemon G/S/C - Final Battle. One of the most awesome maps by Larto, I held the #1 for a good amount of time until Cookiezi came. Try playing it, it's really awesome.
http://osu.ppy.sh/b/699 -- Taiko no Tatsujin - Saitama2000. This was the first sign of Taiko life in osu! grounds, made by the discoverer of the Saitama monster himself, Kharl. The map may not that be impressive for today's standards, but it's reasonable enough for sightreading and is relatively easy as long as you have the patience to keep squinting at the small circles. I had a really fun time getting #1 on this until White Wolf came. Plus, this is my most favorite rhythm game song of all time, so there's some bias here lol.
http://osu.ppy.sh/b/27466 -- Nobuo Uematsu - The Fierce Battle. FFVI soundtrack ftw. [Omega] is so annoying but impressive at the same time that I kind of played it for a while.
http://osu.ppy.sh/s/22404 -- Chata - Yuujou Pop. The [Ai] difficulty on this is an example of some maps that make me regret retiring from osu!standard. I played it for a while and it's really, really good.
There are a few more from before which I forgot to put in my Favorite Beatmaps list so meh.
Also notice how most of these songs are of either the Video Game genre or is a remix of another video game track. Yep, preference for Video Game music over above anything else.
