About every 6 or 7 songs I'd do a drop or some silly made up commercial just for a laugh. I just mixed them up enough so nothing seemed in your face. My listeners know who I am and what radio station they were tuned into so I never felt the need to bombard them with idents or too much chatter. Just getting on the mic and talking a little about the songs that just got played and maybe a short story about one of the artists is good then give them something to laugh about and its back to the music.
