Network your music with DAAP for Linux (Linux.com)
The more music you have, and the more computers you use, the bigger the hassle it becomes to try to synchronize everything. Without a simple sharing solution like DAAP, the easiest way to manage a centralized music collection for multiple PCs is keep all the files together on a central server, shared through Samba or NFS. DAAP accomplishes the same goal with far less administrative overhead, and provides interesting features like smart playlists at no extra cost."
