An empty street, an empty house

Westlife has got a hold on me. Well, not a really tight one...but one that's just constantly there, and I feel it from time to time.

An empty street, an empty house, a hole inside my heart.

It's surprising how often these lyrics (from the song My Love) just pop into my head (with the tune). Why? I have no idea. It doesn't happen with any other song... Some songs pop into my head and I can't get them out for a few days, but they always end up leaving me alone.

But these few lines...they come, they leave...and they come again. Might they be friends? (constantly there, like in the quote I posted before)
