Looking for music to put on a mothers day cd.?

for mothers day i'm planning to make a cd for mum. she really likes angus and julia stone, florence and the machine and kate miller heidke, and i was wondering what other songs she might like. i had thought maybe adele, the kooks, mumford and sons and bands along those lines. do you agree with the bands i already have, and can anyone suggest some more songs/bands that would be good? thanks xo
