At what point will I bog down Ma Bell with audio files that are too large?

You have any advice on the type of music, style, size for DSL or Dial-up,
etc to add to this site?

At what size of a audio file is the top most limit? Similar to the top
limit of catching crawfish or alligators around the New Orleans area.
