Don't much care for Last.FM radio but I love Pandora. I haven't heard of Slacker so I'm checking it out now. - Paul Wade

Use Pandora, never really used Last.FM - Andrew Leahey

love pandora, but no storm support :(. in my opinion these are all very similar so it is just personal preference i guess, but in my opinion pandora seems to give you a better mix of music. - Zach Scott

I've been using Pandora for a while but I stumbled across Slacker the other day and it looks well built, although I haven't spent a lot of time using it yet. - Ethan

I've found that Pandora has the best Electronic music selection, Last.fm the best rock selection and Slacker the best UI (at least in my opinion) with a great overall selection of music. Don't know why I use all three though, guess I'm a bit schizo with tech. - Steve Sebestyen from twhirl

Pandora by far - TheHenry

Last FM by far - Jamie

Pandora if I could hear it but Last.fm me, though not really tried Slacker, is it good? - Kol Tregaskes

I wrote a blog post about this subject back in July '08 that still represents a solid opinion of the state of the various services: http://nathanchase.com/2008... - Nathan Chase

That's why I've not tried Slacker, must be US-only! :-( - Kol Tregaskes

Neither! Spotify! =D - Daniel Bruce

Now that I think of it, I've been using Grooveshark to play specific songs. - Ethan

Spotify isn't available in the United States. :( - Ethan

Yep Spotify works in the UK atm, at least something does, hehe. ;-) - Kol Tregaskes

Used to use Pandora, but they stopped me from accessing it. Moved on to Last.fm, now they've restricted access too. Where do I go now? - Rahul Das

Why have you been blocked, Rahul? - Ethan

@ethan not me personally. The entire world except the US and in the case of Last.fm UK and Germany. Apparently the record labels don't want us listening to their music. - Rahul Das

Oh, I hadn't realized that. - Ethan
