I’ve used the Soulseek network for quite some time now. On Windows, using the official client and later on Mac OS X, first with a self compiled version of Nicotine and later with souseeX — which hasn’t been worked from 2006. When I was already considering moving to Linux I used SolarSeek briefly as well, which has been a promising and beautiful client for over two years, but still hasn’t published fully featured stable release.
On Debian I used Nicotine+ for a while but since I’m running KDE 4 I’m trying to minimise installing GTK applications and use Qt 4 ones when available, because they integrate so nicely with KDE 4. I stumbled upon Museeq — which is the Qt version of Museek+, which is in turn a fork of Museek — as my replacement for the GTK based Nicotine. It’s a bit of an awkward beast, because of the daemon you have to configure before being able to use the application, but all in all it’s very nice. They offer deb packages for both Debian and Ubuntu, so I can use the Qt 4 version instead of the older one in the official Debian repositories.
The only thing missing in Museeq is an Oxygen icon set, as the default one still uses a mix of Qt 3 and other icons. Because of the unavailability of said icon set and my rather inane desire to have good visual integration across applications in KDE 4, I decided to do the icon set myself. So I present you with the Oxygen icon theme for Museeq (choose “Settings” > “Pick Icon Theme” and restart the application).
It’s not perfect, almost all default icons were replaced (except for the IP icon) and I modified some of the original Oxygen ones to fit the specific application features of Museeq better.
