I have a fairly large music collection (about 30,000 tracks) and have been using Foobar on Windows to manage it for years. All of my music is very well tagged, but I have created some custom tags that I use to help create playlists and customize the layout of Foobar.

I have been looking for a Linux equivalent for a long time but have never really been able to find one. I know that I can use Foobar with Wine, but it does not work seamlessly that way and I would much rather use a program that was built to use on Linux. Can anyone suggest a Linux music player that will support custom tags (creating playlists from the tags is more important than layout, but both would be nice)?

Thanks for the help!
