it allows you to create a playlist full of music,which you can embed into like a whole bunch of websites.I embed all of mine into ArmorWiki though.It's completely free,but it may not have absolutely everything you are looking for,but it should have just about everything.Just not some of the less popular songs.Also if you want you can become a member of ArmorWiki,and I will embed your playlist for you on there,where you can access it easily anytime you want,or you can embed it into your profile page on there,but mainly that site is always a good choice.
