All Music Services

The Bottom Line: The V Cast Music with Rhapsody experience is easy to use and understand, and, by combining both the mobile download and the Rhapsody subscription service in one monthly plan, delivers considerable bang for the buck .

The Bottom Line: If you have CDs that you don't want anymore, you can trade them on Lala.com, a very cool online swap meet that also offers Internet radio stations and compelling community features.

The Bottom Line: The intuitive and aesthetically pleasing Zune Marketplace works well as an audio jukebox and Zune companion, but it's missing some key ingredients that would make it a one-stop shop.

The Bottom Line: Despite some glitches, MTV Urge is one of the best subscription music services we've seen to date. If taking your choice of millions of songs with you anywhere sounds appealing, make sure you check out this offering from MTV.

The Bottom Line: AOL Music Now, currently in preview, offers great new features for those who use multiple PCs but still needs to work on the basics.

The Bottom Line: If you are prone to Big Brother paranoia, this is not the program for you. But if you couldn't care less whether a company or a label monitors your tastes, you'll be rewarded with gobs of new music--and an easy method for navigating it all.

The Bottom Line: While not without its annoying flaws, Pandora is an interesting idea that will undoubtedly guide even the music übergeek to new discoveries--and it's free!

The Bottom Line: The Sprint Music Store fits the bill if you're looking for instant gratification on the digital music front, but the $2.50-per-track price tag is hard to swallow.

The Bottom Line: The updated Yahoo Music Unlimited subscription service has more to recommend it than its low price.

Specs: Windows

The Bottom Line: Winamp is still a fun player for customizing your playback experience, but most users will prefer the all-in-one experience of Windows Media Player or iTunes.
