My current favorite music player on PC is Quod Libet. It gives a bit of the old FB2K vibe with how its music selection works as well as all the plugins. I use it on Linux, but I know they have a Windows version as well.

I used Openbox directly without a DE for a number of years on my netbook. It was perfectly serviceable for that use case, but I don’t think I’d have been as happy with it for my main workstation or personal desktop.

Very low bandwidth or resource usage would be some advantages, less so since they made in this java heh.
