Yes you can, but it is very, very difficult. This article has nothing to do with CD-Rs or MP3s, but I decided to add it in anyway.
Good sponsors are nowadays very hard to find.
Majority of their advertising contracts ended at the 31.12.2000 and the start of the new year has been very bad for high volume websites and the advertising networks. Many smaller and less professional advertising networks have gone under and many more will in the near future. Even the oldest and biggest players have serious trouble. Reasons for this downfall are various. The 3rd reason that I can think of is the difficulties at Internet trade - online shops and eMarkets aren't selling too well, or making profit.
