Hi Missprim, have you tried easynews.com, you have to pay $10 which is about �5 but for that you get to download 10gb of whatever you like, films, music, application, pictures., they have a 50s 60s sections in the mp3 category I have downloaded many many hundreds of good quality mp3s .
Missprim by the way Limewire is a FILE SHARING program which allows other Limewire users to browse what you share,(hence the name fils sharing) but even a amateur hacker who also uses Limewire will be able to hack right into your pc and delete/steal/change whatever he likes on/from your PC,
