From the work in progress world owner's manual (ie it might be wrong, but I think it's right cos mit probably wrote it):
------------------------------------------------------------------------------------------------
The world's 'Radio' allows you to create a selection of mp3 or .ogg tracks for your visitors to listen to. There are 3 methods for using the radio on your world..
Link to a shoutcast station
Link to http (webserver) downloads
Download direct to players from your server *
* Of the 3 methods, the latter is least recommended - using the server's bandwidth & download system to transfer large files will cause lag for anyone visiting your world and will result in more connection errors - players getting kicked off your server etc. Use shoutcast or webserver downloads whenever possible.
Note : to make your server recognise any changes you have made to the 'RadioList.txt' file (or any mp3s you've added to your Radio folder) use the command *radiorefresh.
Link Radio to a shoutcast station
To link your worlds radio to a shoutcast radio station, create the following file in the server folder..
Data\Radio\RadioList.txt
Edit this file in notepad and edit it using the following format..
shoutcast=Station Name
shoutfile1=
http://64.236.34.196:80/stream/1076
.. where the 'Station Name' is the name displayed on the client, and 'shoutfile1' is the path to the active shoutcast station (not the .pls file -The ability to reference .pls files will be added in a future revision. For now, you can find the path from a pls by opening it up in notepad or similar)
Link Radio to http downloads
To link your worlds radio to a selection of http downloads, create the following file in the server folder..
Data\Radio\RadioList.txt
Edit this file in notepad and edit it using the following format..
station=StationName1
track=
http://webaddress.com/music.mp3
track=
http://webaddress2.com/moremusic.ogg
station=ADifferentStation
track=
http://webaddress3.com/test.mp3
etc
Note that the presence of a 'RadioList.txt' automatically disables the alternative option of....
Use local server folders for radio
To have music files stored on and downloaded from the world server, you first need to create a subfolder inside the Data\Radio folder. The name of the subfolder is the name that the radio station will have.. so, for instance, create a folder..
Data\Radio\JazzFM\
then the radio will have a station on it called "JazzFM". Put .mp3 or .ogg files in that folder and your players will be able to listen and download the music.
You may also need to make sure that the number of downloads is set appropriately in the server options menu. (It defaults to having a 0 downloads limit - as enabling the server-based radio feature can significantly increase the amount of bandwidth your server uses, and generally cause more lag for players)
Automatically launch your Radio
Use the *settings -> Landscape -> Auto Radio set to 1 to have your world's radio station activated automatically whenever a new player joins.

So the answer to your question is yes, you can use webspace if you use the format explained above.
