bliss should be able to identify music files without tags or empty tags and offer to tag them with information from online music databases.

bliss should find art at http://www.albumartexchange.com/

There's lots of very high quality art there.

Comprehensive tag editing. Ability to distinguish between id3vX versions and independently edit or delete. Complex rule based tag editing.

Those of us with large collections have to put them on several HDDs. I would like to be able to monitor my D:/audio & E:/audio concurrently.

bliss should add a Replay Gain or volume levelling rule so that all music in my music collection can be levelled for volume.

As discussed: http://www.blisshq.com/music-library-management-blog/2010/11/03/mp3-volume-replay-gain/

When a new version of bliss is available, it would be cool if you could be alerted to this from within the web app and also upgrade just by clicking on a button

bliss integrates with iTunes by editing the music files that iTunes reads into its database. For artwork, it embeds the artwork into the file.

However, iTunes does not know that tags have been changed or artwork has been added. You have to use the "Get Info" option in the iTunes interface, for instance, to force iTunes to rescan for artwork.

Instead, bliss should tell iTunes that it should rescan automatically, once tags or artwork have been changed.

Note that a separate idea for rescanning iTunes when file locations have been changed already exists: http://bliss.uservoice.com/forums/21939-bliss/suggestions/1450921-update-itunes-database-when-bliss-moves-files

Different music systems/apps use different naming conventions, and it would be helpful to be able to rename and/or duplicate existing art to work with those. Rules could be added to allow multiple art files in a folder with certain names, or enforce that only one would remain with a certain name. Also, the rule should be able to enforce no separate art, or just ignore separate files altogether.

Imagine I have the file org and cover art rules enabled and my music library has been scanned. I want to simply fill in all missing art first, but all albums with non-compliant file paths will also be listed under the 'uncompliant' filter.

I'd like a more specialised filter that shows [un]compliant albums for each rule. This way, I would be able to see all albums that have uncompliant genres, or compliant cover art.

Reprise is not an allowable genre Allow genre: 'Reprise'

It would be nice if the system gave me the allowed genre's so that I could pick the correct one off a list. As it is, you can't change it at all, and have to use a tagging program.

do a dry run especially for the freeware;
seeing the amount of "fixes" suddenly go down on my live library was terribly frightening.
I really need to know what will be changed where, my library is too large to let random software do something on it.

Having a seperate web page that can view your collection (from chosen location) and browse the album art assigned - from this you can choose to correct artwork through bliss, this would be an excellent way of browsing your collection and correcting artwork once bliss has finished scanning

Any way for Bliss to support AIFF files? Most of my collection is AIFF and I would gladly purchase Bliss if you were to suppport it

Currently, when I configure my rules to require year and genre information, bliss finds all albums without that information and where possible offers alternatives.

This should be automated, so it works like the cover art lookup.

The activity page tells me about the compliancy of my collection but I can't see what has been fixed. I can tell some fixes have been used but not sure what on (I wanted to check that I liked what it had fixed). Also, it would give me an idea of how far 1000 fixes would go if I bought them.

have a button to open an album's folder in the os on the album detail page to let the user manually examine/fix files/folder.

I have several albums for which bliss inserted a cover.gif file in the album directory. What I want is only cover.jpg files, not gif files.
Examples:
artist = Stephen Gately, album = New Beginnings
artist = The New Tradition Chorus, album = Broadway
artist = Grandma's Boys, album = When the Toy Soldiers Marched on Parade...
artist = Platinum, album = Auld Lang Syne
artist = Shania Twain, album = Come on Over
artist = The Beach Boys, album = Made in U.S.A.
