1. MusicLamhe.com It is the fastest growing Mp3 Search Engine. Actually i love this site.. It is Too much Simple and Clean look that attract people. More than 1  million user per month.  Another best feature is Amazing Speed, and one more thing clean about copyright policy. One bad thing is that the Player is missing.
2. http://Beemp3.com According to me its the second and popular mp3 searach engine. Not too much clean look, and too much tough to Download.
3. Emp3world.com another good website.growing smoothly.. but oldy look i dnt like it.But very easy to download.I mostly like it bcoz of all most all English song are available here.
