We're not quite to the point where the migration is completely and utterly dominated by redstarts, though we're getting close.
Chestnut-sided is one of the more dominant songs (excepting redstart and to a lesser extent Tennessee)...
Magnolia is very common too, though it's plainer song is easier lost in the background.
I've never picked out the song of an Orange-crowned, whether because they tend towards silence of if it's just that I don't hear it I'm not sure. This one threw me off a little and is much brighter yellow beneath than most that I see.
