Yea, I get that error too sometimes, I find if I just use another program to change the bitrate it works fine, but yea... I hate lowering the quality of my music.
Although I am relatively new here, I hate working on a piece for hours and hours, think it's good, and then have it recieve a 0 for a rating. They never get reconized. I feel pretty bad for all the people that upload their songs and have them get a total of 4 or 5 downloads total. Atleast mine have had some recognition, but I still get that awful feeling when the music drops down in the abyss where no one will see it again. And then therea re people with double platinums on every song. Sure their music is very good, but sometimes I do they that they get a little too much spotlight sometimes.
So that's my rant. Don't do that too often, but it feels kindda good to say it.
