I usually don't leave a review of a porgram unless there's some sort of constructive c riticism to give. I' rarely leave something simply because I'm impressed.

This thing is SERIOUSLY WEIRD. Right now it's followed "Ruben Remus" by The Band, and old '60s-style classic rock tune, with "Red Chair Fade away" (early Bee Gess psychedlia), followed by "I Bleed" by Homer (sort of grunge-y pop) followed by "Halo Of Flies" by Alice Cooper, and the whole thing WORKS as a mixtape. Also on the same list are Police song, a Cornershop song, an Opal song.. Even though it sometimes pickes someting from a genre that doesn't look like it should belong, when the song comes up, it fits in sonically. Astounding.

This thing works. It's totally weird and totally great. I don't know how it makes its decisions but it really comes up with interesting mixes that are unexpected, and sometimes don't make intellectual sense, but make musical sense when I listen to them. How can a machine make a mix a human finds both interesting and relevant, but not repetitive and boring??? A list based on an old Sister Rosetta Tharpe song includes The Chieftains, Lightinin' Hopkins, The Band, Spooky Tooth and - believe it or not - a GG Allin (!!) song that actually fits the mix! ("Carmelita", if you must check it out to confirm this for yourself.) A mix based on a Skinny Puppy song, however, includes songs by Black Sabbath, Laibach, Gary Numan, Zappa, Amon Tobin, the Descendents. and one of Van Halen's later, more studio'ed-out songs. It also threw an Al Green song into that same mix - but one with a strong bass/snare rhythm. How does it do it?!?! I've only played with it for a few hours, but I put it through its paces, and I have yet to hear a song that sounds totally out of place.

This is like listening to a great, eclectic radio station, helping me discover all sorts of great stuff buried in the thousands of strange albums that mysteriously appeared on my hard drive over the last few months and were definitely legally purchased and ripped by me while sleepwalking and not pirated over the internet.

My big complaint? The free version loads up playlists with too many songs from the same artist. Uh-oh, might have to pay for this one. ;->

Slight complaints... I hit the "Tutorial" button on the analysis screen and get a blank help viewer, hence a lower rating for support/documentation. Also, the browser should show the Album in the song list. And you should be able to rate songs by stars like in iTunes, and maybe even respect iTunes's ratings, and only make playlists with songs you've marked as having a certain number of stars, etc.
