I'll try to contain myself to just one. I didn't notice this on the list, and it most definitely needs to be there. Love or hate it, you can't deny everyone needs to hear it at least once:
My Bloody Valentine - Loveless
Along with Slowdive's
Souvlaki, this is one of the few "must listen" shoegaze albums out there. It will make or break your opinion on that very niche style of music, and for that reason it needs to be on this list.
