#3 SMPlayer

SMPlayer is a cross-platform free and open source multimedia player so it is extremely compatible wherever you want to run it. It supports nearly every possible format you can imagine. SMPlayer can remember settings on a per-file basis. So, you can expect it to remember where you stopped playing, and begin from the same audio track.

#2 Synapse

Synapse goes beyond the simple application launcher to tightly integrate with your Linux system. You can quickly access any recent action you've performed so you can return to it or perform something similar in an instant. It is very quickly due to its heavy assimilation with the Zeitgeist framework.

#1 Synaptic Package Manager

Synaptic package is the graphical user interface front-end to the Advanced Packaging Tool manager. It enables the user to install, to upgrade or to remove software packages. To install a package a user must search for the program they want and mark it for installation. Changes are not applied instantly; the user must first mark all changes and then apply them. It was a standard feature of Ubuntu until it was replaced by the Ubuntu Software Centre.
