I got some suggestions from the comments so here is an updated version of my radio bumper for Team Obliteration. There was a long pause before the Harry Potter music started so I added “ds106 radio” in there. I didn’t add our team name or theme because we talk about that in the introduction of our radio program. You will see

I got the songs off my iTunes.. they are as follows:
Summertime – Sublime
Summer Girls – LFO
Summer of ’69 – Bryan Adams
Boys of Summer – Ataris (it’s a remake- but a damn good one)
