Figures released by the Irish Recorded Music Association (IRMA) reveal that shipments fell 10% in volume in 2007, with trade revenues down 13%.

Mirroring global trends, illegal file-sharing is being blamed for the drop, with IRMA CEO Dick Doyle claiming that for every album bought in Ireland, 20 are downloaded from unofficial sources.

"The market is down 10%, which is the fourth year in a row that we are down double-digit figures," he said in a statement.

Total shipments were €110m ($161m). Leona Lewis, winner of U.K. reality TV show "X Factor," had the year's biggest-selling single and album with "Bleeding Love" and "Spirit" respectively (Syco Records).

IRMA says the figures show that four out of every five singles in Ireland are now bought as downloads, rather than as a physical release.
