Why do radio jockies play songs in exactly the opposite order in which they announce ?

if not clear please ask for clarification

It is done to "tease". Even though shows are "voice tracked" (pre-recorded), 99.9999% of the DJ's do their homework and are on top of the order the computer will spit things out. So by announcing a song that won't be played for a while, they will have you tuned in a longer period of time waiting for that song... it fights your impulse to flip stations. The goal is to get you thinking, "I want switch to xyz station, but the DJ said abc song is comming up, so I'll keep listening to this one instead of switching."

As far as other comments of all this pre-recorded stuff, it's true, but most DJs are hard working individuals. If the weather changes, they will update their voice tracking to reflect that change. If some major event happens, they will come into the station to update thier voice tracking to be current. Even though many shows are voice tracked, many stations know how important it is to have someone in studio. Breaks may be recorded, but the DJ is still in studio recording those breaks just prior to insertion to the program. So the show still is essentially live. And stations still do have times where they are open for requests and accomodate requests with an announcer in studio.
