That would be the menu icon.

Firstly which alsaplayer version are you using?
If you are using an old rpm then you should update your version using a
new one from the website. I recommend getting the tarball. it is simplay
a matter of ./configure;make;make install.
If you already have that or even better a fresh cvs version, have you
set up a file with fake cdda tracks in it?
eg.
mkdir cdtrks
cd cdtrks
touch "track01.cdda" "track02.cdda" ....
Then you should open a playlist in alsaplayer and load those tracks as
if they were oggs or any other sound file on your hdd.
One day we will get around to making those internally.
There is also some support for telling you how many tracks the cd has.
If you are interested in the code. You can find it in the
input/cdda/cdda_engine.c file. You just have to uncomment the
cd_disp_TOC function and also the check for it in cdda_open then
recompile and you when you use a cd alsaplayer will spit the table of
contents out into the shell.

Thats the playlist button.
It is worth doing but not high on the TODO list, of course if you had
the inclination....
