song sites?

hi, im looking for any jap song site where i can dl, well, japanese songs, does anyone have any? and i dont mind if i have to direct or use bt to download, i just need someone to help me find some songs and singers that i really like.

and can anyone help me find songs and artists such as:

Bon Bon Blanco - their group and a song they sang called Yura Yura Yureru?
flow - mainly all their songs that i want >.<
Last Alliance - i just started to listen to them XD

if someone can help me, then i might ask for help on other singers later on, so can someone help?

http://www.jpopsuki.com/ <- possibly the best Bit Torrent source for any Japanese Music / Band / Album / etc. on the net.

Sure you might say #Nipponsei, but they only host anime music. Jpopsuki hosts all music. Just register a free account with them and viola~

I did a quick search and they do have Bon-Bon Blance and Last Alliance. And, of course, flow... who doesn't have flow?

Thank Youuuuuuuu
