Ok I have a 2.53GHz Intel Core 2 Duo 13' MacBook Pro. I would say that about 75% of my memory is taken up by my music (I have almost 25,000 songs on my iTunes) and recently I've noticed my computer slow down remarkably. Is there any way to put this music on some external memory while still keeping it in my iTunes. I guess an alternative would be to keep all my music on my notebook hard drive and any future things could be kept externally. I would obviously not be able to keep an external HDD attached to my notebook permanently but is there any SD card I could use or something to that effect? Thanks in advance for any advice! P.S. - If there is no solution to this, I will probably just end up getting the new MacBook with the most storage.
