Administrators Deloitte said staff had been made redundant across HMV's head office in Marlow, Buckinghamshire, and its distribution centres, but confirmed retail jobs remained unaffected and all stores continue to trade.
Workers announced their sackings earlier today via HMV's official Twitter account. The company's 62,561 followers were made privy to the company's inner turmoil when someone inside the company tweeted:
"We're tweeting live from HR where we're all being fired! Exciting!!"
"There are over 60 of us being fired at once! Mass execution, of loyal employees who love the brand"
"Sorry we've been quiet for so long. Under contract, we've been unable to say a word, or -more importantly - tell the truth"
One tweeter then wrote: "Just overheard our marketing director (he's staying, folks) ask 'How do I shut down Twitter?'"
"So really, what have we to lose? It's been a pleasure folks! Best wishes to you all!"
Nick Edwards, joint administrator, said: "Since our appointment as administrators over two weeks ago, we have been assessing the financial position of HMV.
"Following this review, a number of redundancies at the head office and distribution centres have been made.
"Although such decisions are always difficult, it is a necessary step in restructuring the business to enhance the prospects of securing its future as a going concern."
