It used to be covers, but about a year ago they moved to original artists and more well known tracks. I'm not sure they have got this right and it even seems to be the same music in all lounges and Room. But some of the covers were quite absurd endeavours, so it's better than it was. Town Called Malice wasn't really intended for use in an airport, I suspect, but it's actually a genre derivative from Northern Soul (50 years old this year) so maybe it's OK.
