SongGenie in theory would be a killer app, just like TuneUp, but would be stars are both plagued by lackluster performance and crashiness. I've tested TuneUp but I bought SongGenie and kinda glad I went with SongGenie instead. I'll address later..

SongGenie at $29.95 is just damned spendy for what it does and how it performs. SongGenie is 1/2 of a two suite music collection organizer, CoverScout and SongGenie. CoverScout being the buggy and useful cover art finder and SongGenie being the song identifier. Each is meant to reorganizing expansive collections by first identifying the music and then next finding the cover art. Both apps were very crash happy, often quitting. However version 2.2 of CoverScout finally seems to get things less crash happy, possibly due to the developers axing PPC support.

In a perfect world, one would simply click Identify and the App would go about its business by analyzing the song and then suggesting the proper title. However, its not quite that easy. CoverScout repeatedly times out on identifications (slow, but I'll forgive the speed) only to re-identify the same song minutes later and have it properly find the right information. It makes me wonder what sort of method the developers are using to ID songs and if they're piggy-backing a free service. Once identified, it then lets you click on said fields you'd like to change or apply all the changes to a song or batch of songs. Applying to batches of songs might be great in theory but take a classic artist like Al Green, the man has made music since the 1960s to present, and has had plenty of "Best of" or "Greatest Hits " collections. Often albums will identify songs as part of another collection. There's no "brains" for an album identification, you might end up with a track from one album being suggested to be part of some obscure multi-disk collection. You're left often reviewing each song's change individually due to the lack of smarts.

It can find songs that are "Various Artist, Track 1" and identify it, but it might take more than several tries.

SongGenie also is pitifully slow at loading your library, with 20,000 songs it takes me in the hours to load my library, I believe about 2.... on an 8-Core Mac Pro with 16 GB of RAM, on an external eSATA drive.

Next, at $29.99 asking the user to pay equally to identify album art seems painful to see ask when iTunes does it for free on properly tagged albums or properly tagged according to Apple. Sure it does a better job but not so much that I'd pay for CoverScout.

However, when it crashes it doesn't' bring iTunes like TuneUp which will crash too, but instead often bringing down iTunes AND sometimes forcing you to restart. Plus, TuneUp charges yearly or expensive "LifeTime" although from what I've read others have had to pay to upgrade despite lifetime, and its service is broken up to MANY more apps. It offers more but seems to be trapped to the same performance and stability problems.

SongGenie is a tough buy, when it works, its a beautiful thing and I'd accept sluggish performance if it worked, but either the dev needs to sell this cheaply, like its worth $10 tops or seriously ramp up the production. I want to love this app, I really do

Pluses - Found about 90% of my library's (~35,000 songs) lyrics. Corrected many song/album titles.

Minuses - Doesn't seem to recognize about 50 or so songs that already have all the correct info (all it seems to see are the song titles on these files.) Sometimes seems to drag the whole system down. Frequent crashes when doing lyric searches, and takes quite a while to relaunch.

I bought this mainly for the lyrics auto-fill, which works most of the time, so for that I can give it a lukewarm thumbs-up. Still, it seems kind of buggy. I'll revise the score if this improves.

This is great application, I use it quite a bit. There are few items that could use some improvements, my personal Hindi/Urdu music is sometime problematic but it does a decent job of organizing it, the more popular foreign even adds lyrics (romanized). I think some of the reviews are completely unwarranted. This application works great with Cover Scout . . . and no I have no association with the developer other than a customer. =)

I was in the market for this class of app, and was going to buy Song Genie 2, but some of the reviews dinging Equinux as a company made me buy Jaikox instead. I was very dissatisfied with Jaikoz-- it tagged a lot of things incorrectly, and the interface was painful to look at and use. In the end, I decided to go with my gut and get Song Genie 2, like I had originally intended, and despite having to purchase them both, I am now happy because SG2 did a fantastic job tagging, and the interface made it much easier/more pleasant to fine tune the things it didn't get perfectly.

For those who are complaining, I am a bit surprised.
I was also annoyed by the updgrade price. I wrote to them and they were very comprehensive by offering me another 25% discount on the upgrade !
