I DJ for a radio station, its rad, just pick what song u want to play b4 u go so ur not searching while ur there. Also, you what ur crowd to get hyped, yet still be able to dance. The difference between a good dance and a bad dance, is the DJ. Also, you should def talk on tha mic, get people to laugh etc... iintroduce tha songs, say why u liked it, why u picked it etc...
