I would not recommend Imesh. To download it you have to download "GAIN" ad software--it is not a choice, without GAIN you don't get IMESH. We started getting popups, more and more until months later your computer would not work for any program but being online. DH tried to fix it to load turbotax and lost my hard drive--AND my 250 downloads! Yes IMesh is easy to use, but getting all the ads and popups is NOT worth it.
Since then I have tried Win MX (they said I don't have some sort of TCB port and even though I have a cable modem they have me on dial up speed--I got 2 songs but it took most of one day, forget that) and then Morpheus (almost IMMEDIATELY my computer slowed WAY down so I got rid of that one fast).
Kazaa light is on my list to try, possibly itunes, still looking for that magic sight where I can even find the old stuff and not get a ton of spyware with it.
