On occasion when this app works, it is really good. However, user experience is marred by frequent crashes, only partial loading of iTunes library and often very slow search process. For no apparent reason, Tagalicious often only manages to write the new tag of a single song from an album. The other songs all get red exclamation marks without any obvious reason for that. I have checked permissions and what not, to no avail.
IMHO, this program needs much more work invested before it becomes mature enough to recommend it.
However, potential is clearly there. I just hope the developers come through with frequent updates.
Right now, it´s a 70% write-off for me

The Mac Version is really slow compared to 2007/2010 on the Windows side of the fence. Featurewise, 2011 ticks a lot of boxes but I find the interface, especially the HUDs incoherent and at times downward distracting. Even though an apparent effort to make 2011 gel with OS X is apparent, I´d personally prefer to have 2011 more in common with 2010 which most of us use in the enterprise environment. As I said, speed is also very much an issue, especially in Excel.

Really nifty and powerful tool albeit pricey at 49.99.
You can get much more powerful software these days priced around 50 USD. After all, ABFR is a rather small tool.

While I like the functionality of this programm it unfortunately crashes Safari within a few minutes after launch. This occurs with 10.5.2 and all updates.
