i can't play audio cd

First of all:
Thank you about your work (sorry my bad english)
I have been using your program nearly three years,everyday at work.
Now (from the version 0.6.2,0.6.3) i have a problem about to play audio cds.

This is my entrance from terminal:

pepe@pepe:~$ listen
No musicbrainz support (musicbrainz2 missing)
No avahi support

So i was uninstalling version 0.6 and installing 0.5 from ubunutu's repositories and it work perfect,like before,no problem to play audio cds.
I could play audio cd with Rhythmbox,Vlc,(not with totem.....Totem could not play 'cdda://sr0/Track%201.wav'........There is no input plugin to handle the location of this movie)
Ubuntu is mounting the audio cd ......cdda://sr0/,so i could see every track.
I was trying,draging and droping a file from cdda://sr0/ to listen interface but nothing happen.

Another question.

Using any version....sometimes the program get blocked and i just could see a white screen,the playlist is not working,nothing,so i have to force to close the program and restart it again. (using ubuntu and xubuntu from 7.04 t0 9.04.
Albums with the same name but diffrent artist......i have the same cover for all.
A personal suggestion:
Probably could be good to have the option to take (lirycs,wikipedia,lastfm,events,etc etc at the top bar (close to music,see,control and help) to safe space using a small monitor like me.
i think normally we are not using that options so often like just play music.
The visual interface is very iportant to normal users like me.

Anyway.i like your progarm very much.like i said before i am using it everyday at work,so thank you.
