If you are really that sure the music was by Phill Collins then i don´t know the game you want to find.
But i´ll sugest anyway an amazing Tetris clone, and i´m not sure if it was PD (i think it wasn´t). It´s called Start´N Tris.
The background music was catchy, but a little faster than the Phill´s music.
The playability was fantastic (come on, it´s an Amiga, for god´s sake!), and if you get some consecutive lines cleared the screen shakes up and down.
This game is really difficult to come buy and i coundn´t find any reference to it on the Internet. Neither on HOL or on You Tube, but i think i still have and ADF here somewhere...
