here's what I do when I hear a song and need to devine the artist or band.
1). Remember as much of the lyrics as possible.
2). Google the lyrics, i.e. enter the words that I remember and append, lyrics, to the search string.
3). Narrow the list of artists down to recent (electronic) as many originals have been remixed by any Tom, Dick and Harry with a synthesizer.
4). Once I have established correct artist and song, google for a torrent.
works well for me.
