I listened to Yogcast's Diggy Diggy Hole for the first time a few months ago - now it's stuck in my head. Thinking I had finally found a bunch of new songs to replace it, out comes an official metal cover:
Some of the other songs that I tried to use to replace it with were the Axis of Awesome's Four Chords song, Eifel64's Blue Da Ba Dee and most of the extended lyric music videos on the Star Wars Bad Lip Reading playlist.I've also tried some of Cab Calloway's Minnie the Moocher. Then there's the War of the World musical with Eve of the War and Horsell Common and the Heat Ray
All I have achieved so far is to create a playlist of ear worms. To be fair it is not a bad selection.
