Have you ever purchased an app then found out the next day it went on sale? Or worse yet, the next day it’s free? It happens all the time. Apps constantly go on sale for half off or free. As a user of the App Store, it is frustrating when you just decided to make the purchase only to find out you could have waited a few hours or days to get it heavily discounted.

Well in comes a new free app called BargainBin. According to the apptism, BargainBin’s main features are:

•Sale prices updated as they happen
•Price tags that indicate when apps are: Free or Bargains (50% off or greater)
•Filters that allow you to see Free Apps only, Bargain Apps only, or All apps on sale
•Browsing by a specific category or all Bargains
•Browse only popular apps that have gone on sale
•Viewing screenshots of the application quickly, without having to go to the app store
•Viewing application descriptions quickly, without having to go to the app store

Now that’s what I’m talking about. I have had this app installed for about a week and I love it. I check it everyday. Why not? With just the tap of my finger, I can quickly find everything that is on sale or reduced to free. What a concept!

So head on over to the App Store and make sure you install BargainBin. Cause only fools pay full price for apps.

It’s time to break through the clutter and get down to business. This weekly post is going to list not the top 10, or the top 5, but the top 3 of anything gadget related. Why the top 3? Because anything more would be watered down.

So without further ado, here are the top 3 free music apps for the iPhone.

3. American Public Media’s – Public Radio Tuner
You don’t have to be a nerd to enjoy public radio. I do. And this app provides access to hundreds of public radio stations which will keep you up-to-date with the most honest and unbiased take on news available. So whether you prefer to listen to “This American Life,” “Marketplace,” or “Wait Wait… Don’t Tell Me,” this app will hook you up with free streaming NPR anywhere you go.

2. Shazam Entertainment Ltd.’s – Shazam
Who hasn’t ever been listening to the radio wondering what the name and artist of the song is you’re listening to. Well, use Shazam and you’ll never wonder again. That’s right, with Shazam you only have to open up the app, click “Tag Now” and in about 10 seconds you’ll have the artist name, song name, album name and more. You’ll also have links to download the song from iTunes, watch the video on YouTube or read reviews. Now that is sweet.

1. Pandora Media Inc.’s – Pandora Radio
Traditional music stations should be scared because with Pandora Radio you can get personalized radio stations for free that stream directly to your iPhone. No commercials. No bad music. Just create a station based on an artist or song that you like and Pandora instantly starts streaming music that matches your taste. Best of all… no commercials! Sounds crazy, I know. Pandora Radio even learns. Don’t like a song being played? Give it a thumbs down and never hear it again. Plus, I’ve never had an issue with songs skipping or slow playback, even while streaming over Edge. For all these reasons, Pandora Radio is the best free music app on the iPhone and also the reason I will be cancelling my XM account.
