Lmms is only available in terminal

Have you logged a bug...

If you do report this (or any other problem) as a bug in Ubuntu, please make sure to read https://help.ubuntu.com/community/ReportingBugs carefully first, and search to see if anyone else has already reported it. In this case, after doing those things, you could start the bug reporting process by running "ubuntu-bug lmms". (It is good to start your bug reports with Apport because then potentially valuable information from your system is automatically attached.) You should make sure your bug report is complete and self-contained, so that developers can fully understand and appreciate it, even without referring to this question. When there is a question on Launchpad that is related (as in this case), it is good to link the question and the bug together (after reporting or finding a report for the bug) using the "Link existing bug" link on the question page.

If lmms never created a menu item on your computer, or the menu item disappeared in an lmms update, then you should probably report this as a bug. However, if the menu item disappeared suddenly and you don't know why, then I would recommend that we investigate the matter here first, since some condition other than a bug in lmms might have caused that. What exactly do you mean when you say that it is "no longer listed"? Do you mean that it was listed yesterday, that it is listed for some releases of Ubuntu and not something else, that you installed an update to lmms and now it is not listed, or something else altogether?

I see that in this Question section, pretty much everyone has the same problem here. I just logged the bug #824231

More info:
Like the other questions asked here, lmms disappeared from the Sound/Video menu of the Application Menu.
I had to run the program from the terminal, and when I discovered that it functioned properly, I created a launcher button in my panel.

I haven't updated Lmms from the original version I downloaded. If I recall correctly, it happened in the update from Maverick to Natty. It is not a functionality bug (as it runs perfectly from the terminal) so I didn't consider it a problem, until... I couldn't find the program listed in the Software Center. I browse through the Sound/Video section occasionally and look for new programs to try, and noticed lmms was NO LONGER listed. It was previously, but it has since ceased to be in the correct category. you can still find it by searching for "lmms". Like I said this is minor, but if something happened to the software center, it could be a potential bug that could affect other programs. My reasoning to question you initially was, simply that other people looking to use Ubuntu as an alternative, may be lead to believe this type of drum sequencing program is non-existent.

I do not know the exact date when it was removed from the my menu, (as the program runs fine, and I saw no need to contact anyone). I don't know when it was removed from the software center, as I already have the program, and was not looking for it. I simply was browsing through and noticed Lmms was not in the category.

I think it is a great program and want others to find it, that is all. It has been invaluable in what I do. Thanks guys for your valuable time

lmms.desktop is missing from /usr/share/applications/

so here is my version that fixes the problem.

[Desktop Entry]
Encoding=UTF-8
Name=LMMS
Comment=Drum sequencer with multiple plugin and midi capabilities
Exec=lmms
Terminal=false
Type=Application
Categories=Application;AudioVideo;Audio
Icon=lmms

/usr/share/applications/lmms.desktop

is not automatically installed or created, but the above code is a fully functional workaround
