Throwback Thursday – #TBTXPN – is back every Thursday, all summer long. Our first week we celebrated the music of 1968. This past week we dug deep into our record collections and played the “lead-off” tracks – the first songs from the side ones of debut albums. We pulled together a list of the songs we played on XPN, plus more, in a Spotify playlist of 140 + songs – over 9 hours of music to listen to below.
