I pronounce you,
Bokty.com
How does this work?
We merely provide the service to search for music (MP3 or otherwise) by utilising Google as the medium.
Why is this so effective?
We're constantly tweaking the search string to cast aside all the rubbish sites that don't really contain MP3s. In light of torrent sites being under fire, Google is your next best friend for finding music!
Is this service legal?
In one word, yes. However, you must use Bokty only to download music from artists who permit you download music from them.
