Can I just send all of the songs you played in the last plug.dj session?
Why not?
However, as a kind reminder for those who may have understandably skimmed over the OP, a song I already know won't be allowed a quality score above 3, even if I think it deserves a 4. On the other hand, a song I don't know will see its 4 turn into a 5.
Also, for drama's sake, I won't tell you via PM I already know the song you are submitting.
Also also, if you happen to send a song I don't remember but was already submitted in my past roulettes, said song will be treated as a song I don't know.
