MPFree / Online scam
I strongly urge everybody to avoid MPFree, which is an online company at www.mpfree.com. They promise 'free' music in MP format if you click through their e-mail promotions. However, when you redeem your free music, you will be sent to the website called EZ-Tracks (located at eztracks.aavalue.com), and nearly all the songs on EZ-Tracks are horrible covers and imitations of the original artists.
In other words, if you think you're going to download free Led Zeppelin songs through your MPFree.com membership, what you'll get are terrible covers of the song done by bands you never heard of. Further, the EZ-Tracks website, which you have to use to download the music, is documented by McAfee Security as a high-volume spammer! So not only will you not get music by the original artists, you'll also expose yourself to high-volume spammers!
I very much regret wasting my time accumulating 'free' music on MPFree.com. Avoid MPFree.com like the plague folks!
