How to know if my song has been sold?

Is there any way I can tell my song is being sold? To tell that I'm making money off it?
click on your band and it lists all your band's songs.
status: charting means you are selling it at the moment.
click on a song name to see how many units of that song you have sold.
usually songs sell for about 10 days until they are archived and you stop getting money from them.
once you have 6 songs you can put them in an album and make some more money.
Thank you! I'm releasing and album with eight songs and only one single...
