A bit slow. Cluttered. Somewhat confusing. Lack of focus. Really ugly McDonald's ad. Has a lot of potential.

None of the critiques matter much at this point. We're only at day one. The music is free. An ugly ad can be stomached for free music. But the entire experience needs to be improved. And I believe it will. News Corp & Friends are in this for the long haul.

The main page is fairly well curated. The opportunity to buy tracks is there (not all tracks, yet). I'm sure the site will work out bugs, make improvements, add features and add value for artists and labels.

A few more points:

• Even though track purchases are handled by Amazon.com, MySpace Music does not have the excellent shopping experience of Amazon.com's MP3 store. Making tracks available for purchase is only part of it. The key is how music is merchandised and presented to users. Since the end goal is to encourage purchases -- and not settle for song streams -- MySpace will need to work on its salesmanship. Right now it's very passive, like a typical widget.
• Users can add to their playlists audio tracks from MySpace videos posted at an artist's MySpace page. I like that.
• From a political point of view, it's bad that many indies have been left out at the time of the launch. From a practical point of view, it doesn't matter so much. Even the majors have not fully added their catalogs. There are tons of holes to be filled.

Plenty of commentary and first impressions have appeared online today: Idolator, Listening Post, PC World, paidContent and A VC.
