Since Apple has iTunes and Microsoft has the Zune software. Ubuntu should have its own music player like those two other operating systems. Canocial should make its own music player since Rythumbox and Banshee are not cutting it.

You can even tie it into the Ubuntu One music store.

The sound menu at the top right only has volume control.

I listen to a lot of podcasts and need to repeat sections.
Also it would be nice to repeat parts of songs without having to open the music player.

Remote control of media players via smartphones is often not easy. At the moment for every media player someone has to create an app that can control it. This leads to the fact, that this app is often just available for either android or iphone (as is the case for banshee, which cannot be controlled over iphone at the moment). The other possibility is, that people have to reimplement remote protocols over and over again, and I think a lot of development effort is wasted, and we would be better off if developers agree on one method.

If you have many 'Various artists' compilation in your music library, your artists list is full of artist with one song.
You don't usually search for these items and they make the list too long and inconvenient to browse.

Would like an option to disable Artist and Song information popping up in the indicator applet in Gnome. Listening to online radio stations with Banshee has the tendency of popping up information way too often, getting in the way of my work.
