MP3 supersite AllOfMP3 was smacked down last week when Visa announced they’d no longer allow payments to be made to the legal-ish online music store using their credit cards. This effectively shut the site down, because once your AllOfMP3 balance runs out you won’t be able to add funds to buy more music.
All is not lost, however! Your AllOfMP3 login credentials also work at their sister site, alltunes.com and they DO accept credit cards. You might want to consider bumping up your balance over there before Visa catches on!
