I'm sure it's already been decided by the higher ups but I'll still throw in my opinion. The only guy that I feel truly deserves it is:
F777: Besides releasing a good number of songs throughout the year, I believe that F-777 was simply one of the most influential artists here. While he hasn't chatted too much in the forums, he's certainly been present, from music discussions to various MAC's and contests. More than anything he's recognized for his amazing character and personality. He helps and gives advice to ANYONE who asks for it, regularly reviews submissions throughout the portal, and keeps in touch with many of the users on here as friends. His music is also fantastic; all of his submissions are creative and unique, and the fact that he is on almost 2000 fav artist lists is testament to the likability and quality of his music. I would highly HIGHLY recommend F-777 as the main candidate for MotY.
There are many other great people on the portal who deserve recognition. ParagonX9 and Envy for creating such universally liked songs, Maestrorage for running all the contests and keeping our standards for classical music so high, Waterflame for releasing so many songs that went on to play a part in Castle Crashers, MrMilkCarton for loading the portal with tons of high quality trance songs, Reasoner for some god damned amazing music, and many others. However, the only one who really stands out for me as someone who doesn't just excel in one area is F-777. I have seen the portal influenced in so many ways through F-777, and I feel that he is an artist who embodies what we strive to create here on this site.
So that's my opinion :P
