Ah yes the classic DAWG songs.
You might ask yourself what is a DAWG song? As simple as I can put it these are songs that become popular very fast because one group of people cant get enough of them (Drunk A** White Girls).
You might not like them but that is irrelevant because the drunk white girls like them. Clubs will play these songs in full rotation to keep the DAWG songs in the club.
If you can't tell if a DAWG song is playing look for these cues.

Hot beat that makes the whole club shake

Girls scream right when the beat drops and rush to the dance floor.

Guys and girls who do not dance at all will dance only for this song.

Nearly everyone knows the hook and at some point the DJ cuts the music to let the crowd shout it out loud.

In some cases the song will have it's own dance.
examples:
Get Low
Salt Shaker
Let me see yo hips swing
A Bay Bay
Drop and Give Me 50
Low (Flo-Rida)
In Luv with this Club
Independent
Shake that Monkey
I'm in Love with a Stripper
Make it Rain
Freaky Gurl
Holla Back Girl
Back Then

ps...
This is not Just limited to Hip Hop

Pour Some Sugar on Me
Don't Stop Believin
I Love Rock and Roll
Toxic
Sweet Home Alabama
Redneck Woman
