Use MIRC. http://www.mirc.com
It is not the easiest to do, but I found it to be the best
for getting anything you need.
Basically, it is text based
When setting it up, select undernet servers and the "random US server option.
When connected, close the Mirc favorites window
Go to Tools tab, select Channel List
in Match text type mp3
hit the Get List! button
After the list of channels appears and finishes loading,
double click any of them to enter that channel.
I start at the top with the most users on.
Then type:
@find push up rihanna
New tabs will pop up in red at the top,
Follow the instructions in them to download the song.
I found about 11 sources for it.
