Adding a song allows you to add it to one of your playlist, or at least on top of your profile. Liking a song just makes it show up on the "likes" tab of your profile. In both cases, the person who posted the track is notified, and their counters increment.
On the rankings (whyd.com/hot), only "adds" are counted.
EDIT: if you start playing a new song in a new tab it doesn't stop the old one.
