HMV and Xtra-vision, both now under the ownership of turnaround specialist Hilco, reported combined sales of just over €95m between them.
This was an increase of 15% on 2013 levels according to a statement from the company.
The statement did not disclose profit figures but noted a significant rise in CD sales last year, driven in part by a series of new shop openings.
It said that overall CD sales in Ireland were 14% higher last year. HMV and Xtra-vision reported a 51% increase in like-for-like sales, which strips out the growth from outlets opened during the year.
Vinyl's resurgence continues and HMV Ireland said it sold 50,000 vinyl units last year - up 400% on 2013.
It noted that vinyl sales in the week before Christmas 2014 were the highest at HMV globally since the mid-1990s.
Film rentals at Xtra-vision stores fell by 23% due to the introduction of rental passes and customers switching to DVD ownership.
But sales of games consoles and software saw a 7% increase over 2013's total.
HMV and Xtra-vision CEO Gerry Butler said: "The roll-out of HMV departments to many of our Xtra-vision stores has made physical music products available in areas not previously covered by retailers."
"The result has been an overall increase in the market for CDs in Ireland," he added.
He said: "The HMV brand has also helped to drive DVD sales at Xtra-vision stores that were previously focused almost exclusively on rentals," he added."
During the year, new HMV stores were opened in Dublin, Ballymena, Galway and Belfast. HMV "shop-in-shop" departments were also rolled out to 51 Xtra-vision stores.
