What volume should i mix and render my home recorded song at?

Thanks in advanced for all answers. I've just finished recording and mixing my bands new song and although it's mixed i know that once i've rendered it it will not be a similar volume to other artist's music on my ipod for example. Although this may be a vague question can anyone tell me what volume my song should be rendered at to match that of other artists. Thanks, jackWhat volume should i mix and render my home recorded song at?
If you have a sound editor (such as ProTools or Sound Forge), you can compare the volume levels of your existing tunes with the ones you recorded. It may be a little tricky if you did not use any compression or processing to temper your recording, especially if you have a wide spectrum of dynamics in your original material, but you can get it pretty close.
