It is recommended that you have a high speed connection to the internet in order to facilitate and speed download times. The MP3 files are compressed in a zip file which makes the download more efficient but the files are very large and can take hours to download over a dial up connection.
Our server has the capacity to handle thousands of visitors at a time but that is only one component of the process. The other component is the service provider in which you use to connect to the internet. If your server has limited bandwidth it could corrupt your download.
