[ed: found it! i must also add that having a very poor grasp of cantonese i never realised, till i googled the lyrics today, how depressing the lyrics are! ]

i suddenly wanted to hear this. if someone has it and will send the song to me i will love you.

偏偏喜欢你 
作词∶郑国江　作曲∶陈百强　

愁绪挥不去苦闷散不去
为何我心一片空虚
感情已失去一切都失去
满腔恨愁不可消除
为何你的咀里总是那一句
为何我的心不会死
明白到爱失去一切都不对
我又为何偏偏喜欢你

* 爱意是负累相爱似受罪
心底如今满苦泪
旧日情如醉此际怕再追
偏偏痴心想见你
为何我心分秒都想著过去
为何你一点都不记起
情义已失去恩爱都失去
我却为何偏偏喜欢你
