Some 27,000 euro raised in HMV sales for a charity single for cancer sufferer Lily-Mae Morrison are to be paid.
About 300 musicians supported the version of Elton John's Tiny Dancer to raise money for treatment for the four-year-old girl from Galway.
Lily-Mae's mother Judith said the donations were very important.
"We're delighted that the Tiny Dancer invoices from HMV will be honoured," she said.
"This money is very important for Lily-Mae's future and for the future of all the children suffering for neuroblastoma as half of it will go to neuroblastoma research.
"Right now our main focus is Lily-Mae who is a very sick little girl. She and her brother Evan are the centre of our world. We'd like to thank everyone for the continued support."
It is hoped some of the money raised, in the region of 70,000 euro now, can be used to fund treatment for Lily-Mae who suffers from the rare childhood cancer of the nervous system.
HMV's Ireland operation was put into receivership last week with stores closed for the foreseeable future.
It is understood an arrangement was reached between receivers in Deloitte and Lily Mae's family.
Stephen Macken, who produced the new version of Elton John's track, called A Song For Lily-Mae, said it broke into the top 20 in online downloads and almost hit the top 10 a second time after the HMV story broke last week.
