I found this list on About.com and the #1 is
VERY UNEXPECTED to say the least.
10. Star Radio Top 40 Hits
This is another leader among Live365's pop radio stations. Star Radio specializes in a mix of pop music from the US as well as a number of European countries.
9. Z103.5 - Toronto
Canada loves pop radio, too.
8. KISS 108 - Boston
Boston's KISS 108 began as one of the country's top disco radio stations in the late 1970's. Fortunately for the station's long-term existence they evolved into a top 40 station.
7. Rockland USA Pop Mix
Live365 is the leader in homemade Internet-based radio stations. This is one of the best of the pop-oriented stations.
6. Yahoo! LaunchCast Pop
Yahoo's radio stations are rather staid and no-frills, but they continue to deliver solid programming that can be modified based on your personal tastes. A free Yahoo! account gets you access to the main pop stations. A paid membership gets you access to a wider range of radio stations.
5. XM Top 20 on 20
This is the only station in this list that requires a paid subscription for listening. However, it is a fascinating service you receive when you join. This is the only major radio station that incorporates live voting on what music is hot to determine the playlist. Top 20 on 20 is included in the suite of stations available to Internet-based listeners of XM.
4. Star 94 - Atlanta
Star 94 is a flagship pop radio station for the south.
3. BBC Radio 1
The BBC's radio voice is a key player in what music becomes popular in the UK. Thankfully, the djs and personalities of BBC Radio often have flawless taste in pop music.
2. Z100 - New York
Z100 is the top pop radio sation in one of the world's largest radio markets.
1. KIIS - Los Angeles
KIIS of Los Angeles is probably best known as the radio home of Ryan Seacrest. It is also boasts one of the largest audiences of any pop radio station in the U.S. and frequently hosts major artists as on-air guests.

WTF?! KIIS over Z100 and Radio 1?
Seriously? What kind of a list is this? KIIS might have rights to Ryan Seacrest and his AT40 show , but Z100 is #1 in audience,
AND doesn't have to edit their music. Try listening to KIIS for an hour, and try not to take an Advil.
Otherwise, glad to see XM and Radio 1 make the top 5 on this horrific list.
I wonder if ATRL Radio is eligible?
