hello

two separate things here:
1) to upload music in a different server... well, you must do it on that other server! not from music collection (that is literally impossible...!)

2)once the songs are in the separate server, you can tell your music collection to stream from there:
set up the SONGS SERVER parameter to point to the new server. for instance: http://www.externalserver.com

also set the SONGS PATH, for instance /songs on the extenral server

and then, your songs simply contain the name of the file, for instance song.mp3

with all these, this song will be retrieved from

http://www.externalserver.com/songs/song.mp3

But if I create the albums and artists in my site, and only host the songs in the external server, how to i add these songs to the album. Because it gives me only option to browse to add the new songs, which adds it in my own site rather than the external site.

I just told you...
just create new songs, and TYPE the filename of the song (that would be stored in the extenral server), don't use the upload field (because this is for uploading files to the same server..)

okie got that....
sorry... i dint understand the first time
