I never knew how huge Enya was until I joined ATRL tbh.
If you are from US then that's expectable. Americans their ears are so spoiled by an awful music that only 9/11 was able to make them to check out Enya's music (besides LOTR, of course)
Afghanistanet's "successful global arena tour" isn't even going to outgross Britney's Vegas residency, her album got outsold by Catatonic Jean, and No Caree3r got outsold by Living For AARP and Ghosttown. I don't see the point.
Madonna has been more successful than Janet for pretty much ever and Britney is way younger and closer to her last gasp of relevance. Should we be shocked?
