SATELLIO Cool. Reminds me of SoundApp (MacOS 9) :-)
SoundApp had a very cool feature: "virtual" playlists: when you double-clicked a sound file in the Finder, SoudApp would begin playing it, of course... and then when you double-clicked other sound files in sequence in the Finder, SoundApp would add them to a virtual queue. After the first song finished playing, the next double-clicked song would begin, and so on... One could even navigate back and forth within this temporary "queue-playlist", using the keyboard arrow-keys. I liked that.

A contender for SoundApp and Taply? DropSound: http://www.macupdate.com/info.php/id/16112
Gonna try them now (Taply and DS).
