Four Achievements added to the site

In the past two weeks, four achievements were introduced to the site. These achievements allow an alternative way to earn points beyond the basic point gains earned from other people bumping songs after you do.

The achievements are still being tweaked and a number of the level requirements have been tweaked since their initial release (For instance, the level requirements for Sensei of Soul were increased from what it was initially released with and the Disc Jockey level 1 requirement was also raised from its initial release value of 5 listens). Below are the current values as of now (including known point values).
