How do i extend a sound-effect clip???

I have already done that. I put several duplicates of the same clip in a row, but there's a clear break between each clip. For example, the sound-effect clip is rain; so if i copy, paste it and put it after the original you can hear the break between the clips.

There's a way to fix that, i know, by putting audio cross fades between each clip, which works, but as you can tell is a hassle.
I just thought there's was a much easier and faster way of looping the short clip so that you can constantly hear it (without any breaks) for a longer period of time.

The effect is heavy raindrops.
The effect itself is about 10 seconds. So when i put it on the timeline i can't extend it longer than that.
I just wanted the rain effect to last longer, which i can do by copying, pasting the clip one after the other and using audio cross fades to keep it constant but there's gotta be a much quicker and easier way to do this.

I thought there might be a command in the menu that i can press just once to loop the clip.

Thanks.

Yeah your right it does make it a bit quicker.

Thanks for all the responses.
