This is free content from volunteers. I think about how many amazing C3 customs I have and what I didn't have to pay to get them. Then I think about how many songs HMX couldn't provide but C3 has and continues to. Then I read someone posting "You really should have charted [my personal favorite] instead."
C'mon, people, there has never been less to complain about.
Just to add to this ,another thing to remember, especially when there is a pack (and I use that term looslely here) the charters may be charting a song they really don't care for. Nothing worse than charting a song, listening to it 500? times, getting it stuck in your head, hating it even more than when you started and still having to give 100% effort into charting it correctly. At the end of it all, they will get a few "thank you"s and they start the process all over again. Their dedication is amazing.
