Thanks to those of you who responded to my story about changes in the digital music scene.

I listed 10 Web sites where you can find new music. The story was pinned on the news that some formerlly illegal and shut-down sites - like KaZaA, Napster and possibly Pirate Bay - are clawing their way out of the grave in legal forms. It's all part of the Internet's shifting music scene. Streaming music is becoming more popular; buying it, less so.

Many readers chimed in with cool Web sites I didn't include. Here are a few of your favorites, from the story comments:

Amie Street: an indie download site where popularity determines price

Folk Alley: streams folk music

Slacker: one reader calls this "by far the best online streaming site I have seen so far"

Jango: radio-like streaming

LastFM: recommends music based on what you like

iTunes and Amazon: they were left off the CNN list because they're not new or changing, but they remain staples just the same

As always, thanks for the input!

Music producer Danger Mouse wants you to download his album illegally. He is even going to sell you the blank CD-R to burn your ill-gotten tracks.

The "Dark Night of the Soul" book with blank CD-R ships May 29th, and the album again raises questions about how Internet technology can be used to distribute music - and what is or isn't ethical about the process.

DJ Danger Mouse, who is half of the pop group Gnarles Barkley, began stepping on record label EMI's toes in 2004 when he utilized internet outlets to distribute his self-published "Gray Album," which mixed songs from Jay-Z and The Beatles.

EMI, who owned rights to The Beatles' content, attempted to block the album, but people online responded by creating "Gray Tuesday," an organized protest where participating Web sites posted the unlicensed songs for public download. Now EMI is again attempting to prevent Danger Mouse from releasing "Dark Night of the Soul," but he's not one to let a legal dispute keep music from his fans.

A spokesperson for the DJ said: "Danger Mouse remains hugely proud of 'Dark Night of the Soul' and hopes that people lucky enough to hear the music, by whatever means, are as excited by it as he is."

Danger Mouse is still releasing "Dark Night of the Soul," but instead of a 13-track album the case will include a 100-page book of David Lynch photographs and a blank CD-R that is labeled: 'For Legal Reasons, enclosed CD-R contains no music. Use it as you will.'

Legally, fans can hear music from "Dark Night of the Soul" streamed on NPR Music. I listened to it last night and was impressed, but will anyone buy this new album when the music is already freely available?

One of the most exciting tidbits from Tuesday’s MacWorld keynote for me was the announcement of the move toward DRM-free (digital rights managed) music on the iTunes store –- and, more interestingly, the ability to upgrade your current purchased music to a DRM-free format.

If you want to remove the DRM from your iTunes purchases, it's all or nothing.

As I’ve admitted before, I'm a fully entrenched Apple fanboy.  Thus my music player is an iPod and the music I've purchased online is from the iTunes store.  That is a very limited amount of my music –- as I never liked the prospect of “renting” my music, having it locked into a particular format –- especially when I could get the CD and rip it into the quality and format of my choice for my digital devices -– and have the ability to re-encode it if necessary.

So, how do I upgrade my music?  On Wednesday a link appeared on the iTunes store (in the "Quick Links" area in the upper left corner) that says just that: "Upgrade My Library." Clicking on it takes you to a screen that shows you how many songs are eligible for the upgrade.

In my case, it’s 233 songs (more than I thought), which includes about 15 albums, for a charge of $56.70.

Am I gonna do it?  Maybe, maybe not.  First off – it's an all or nothing deal — you can’t just pick your favorites and leave all the junk you bought to rot in the DRM wasteland.  Also, I have to agree with friends, colleagues and Internet commenters who think this should be free –- or at the very least cheaper -– with a bigger discount for larger libraries.  On the other hand, as one of my good friends pointed out, 30 cents is much cheaper than if you had to buy the whole thing again, like many of us did when updating our libraries from cassette or vinyl to CD.

So in the end, “Yay!” to the death of DRM on iTunes, and a resounding “meh” on the paying more to get my music in the way it should have been to begin with.  What are you guys gonna do?
