This program is pretty nice. It still didnt replace foobar to me but the interface and features are quite good. Plus the library functions are easy too.

Cool find! Although, it looks like CD Creator 5 and the program is like Itunes. I don't recommend it though. Give it a 3 out of 5!

[Although I do enjoy the slow to forward song tune when you switch tracks. Audio programs are now going towards too using that feature. WMP11 is going to use it I believe ]

Yes, I might have mentioned wxMusik earlier.
wxMusik is a free, open-source crossplatform music program coded in C++ with the wxWidgets toolkit library.
It is avaible for Windows and Linux.

The guy who started the project is now working on musikCube, but wxWidgets is still being developed. musikCube is very similiar to wxMusik and is also free and open source, however it is not cross-platform.

i used wxMusic... It's ok but equaliser is not changing settings in real time (big fat minus for that!) and you need some time to get used to it (add song, create playlist...)... But that was in earlier version i dont use it now...
