I downloaded several MPEG LAYER 3 AUDIO, the download was successful however I am unable to upload these files to I-Tunes. One of the files I downloaded was from Bhangra section called:
5B_C3_90c_5D_20Babbu_20Mann_20-_20Hashar_20_28OST_29_20_28By.Zorro_29_20_5BDholCu tz.Net_5D_20Jun_202k8/_5B_C3_90c_5D_2008_20-_20Babbu_20Maan_20-_20Hashar_20_28By.Zorro_29_20_5BDholCutz.Net_5D.mp 3

rename the files and try , can be the special character in filenames that is causing the problems
