I guess the "you"-person is all the people who share music here.. 'YOU, ME and all the rest here..

If you find a song that are bad quality.. throw it away and don't "send it out onthe net again"... and the same for all programs that doesn't work because they miss something.
I have downloaded a lot of programs from everywhere and sometimes it takes a while before i check them... but if they are bad.. i throw them. Hopefully others will throw their bad files too.. and don't let them out on the net again...
