Free hosting sites
Werner,
That's exactly right -- they alsmost all have an "upload" function that let's you copy music from your computer to their servers via a browser. A dial-up connection may mean it takes a little longer...
Soundclick.com, myspace.com, ourmedia.com, garageband.com, and CNET's mp3.com are all good free hosting sites. There are a ton available, though some allow a maximum of 2-3 songs.
