I made an account in 2009 after beating Ouendan 2 on Hard. Stopped playing after about 10-20 tries because of my crappy wireless mouse, laggy old single-core PC, and my superior playing skills on DS.
Got an Android phone and downloaded osu!droid in 2011. Didn't play it much, and complained about lag when I did, so I didn't download very many songs (I think I only had 2). Then a year later, my phone decided to kill itself.
Summer last year, I went on vacation. I borrowed my dad's phone and put my phone's memory card in. I had music on the memory card, and was using the phone as an MP3 player. Then I discovered that the phone decided to search for music outside of the music folder. It found my osu!droid beatmaps folder, and
this beatmap's mp3. I listened to it non-stop throughout the trip. Really badly wanted to play osu! at this point, so I downloaded it on my laptop when I got home and became addicted.
