Thats a capacitor and I have soldered thousands of them.
Not that hard, use a 30 watt iron with a pencil tip.
Make sure the tip is clean and run solder on it, shake off the excess and apply the tip to the junction of the wire and the copper trace on the board and the solder almost immediately.
The cap may be polarised so be sure and get it in the right way.
This is something a video would be good for
