A:Answer I, personally, wouldn't use this mic for recording singing or performance-based vocals. If you're good at what you do, spend the money on a decent interface (Behringer Uphoria, Focusrite Scarlet, etc) and a decent mic.
If you have a vocal booth, this mic would work fine. Without a sound-treated vocal booth, this mic is going to capture the room as much or more than your voice. You can try the Samson Q2U or the slightly better Audio Technica AT2005USB if you're looking for a USB mic.
Best of luck with your endeavors. Create, share and keep pushing!
