Apparently hitting the download button counts against your download limit, even if you don't actually follow through with the download. Is this an oversight? It's very unfortunate either way, as hitting the download button is a quick way to verify if you've already downloaded the file. It will show a (1) at the end of the filename if you have. Killed a bunch of my downloads today just double checking lol.
I guess I'll start using the playlist function to keep track of what I've downloaded instead of just looking at the favorites list. It still kinda sucks to be dinged for an oopsie though.
