Does anyone know any good websites where I can download anime songs + Jpop/Jrock??

The program Limewire is rly good for other songs but it's not the best for anime and jpop. If you're looking for anime, I'd strongly recommend Gendou's anime muziki ^^ link
If wewe want jpop as well, wewe can check out link
It also has quite a few anime songs and it's rly awesome too :)
Both websites require sign up but I can definitely say it's absolutely worth signing up for either of them, especially Gendou ;)
Hope this helps :D

websites... no but there´s a program(the one i have) that is very good Limewire and is free

link is a site just for mp3 anime, if wewe jiunge the site and can make as many downloads wewe want, is a Brazilian site, so it's in Portuguese, but just as wewe do the tafuta kwa putting the name of the anime at the bar, not must be hard for anyone not understand the language x3
