One of the major features of the iPhone is its ability to store and play your music library, just like an iPod would. For those of you who don’t like spending the $.99 (or more) for each song you buy on iTunes, there are a plethora of music applications that should satiate your starving earbuds. Just by browsing the the iPhone Apps store, you can find these applications to play music without having to buy it.

Here are some iPhone App Reviews that will hopefully be helpful in your quest for the perfect music application.

Pandora

With Pandora, you choose what kind of music you like, and the application makes a radio station that matches your favorite genres and artists. Unfortunately, there is a skip limit (you can’t skip more than a certain amount of songs that you don’t like), but it displays album art and allows you to "like" or "dislike" a song with a thumbs up or thumbs down, respectively.

Last.fm

Also a radio-like application that suggests songs, artists, and albums that you might like, the application lets you choose songs to play at a later time and add them to your queue. The Last.fm is one of the most dynamic and in-depth music applications the iPhone app store offers.

Slacker

Slacker acts similarly to Pandora, with the "Heart" and "Ban" buttons for you to tailor your music selection more specifically. This interface is sleek, simple, and extremely easy-to-use displaying album thumbnails, with a few buttons at the bottom. Fast, great-quality music – what more could you want?

Imeem

The most outstanding feature of imeem is that it taps into your existing music library and uses that information to recommend similar artists and songs that you might like. Other than that, the program is very similar to Pandora and the Last.fm.

Iheart radio

Iheart radio streams music from actual radio stations in the metropolitan area with less commercials and better sound quality than more FM radios. If you want to hear the most popular songs playing on the radio – some usually lost from listening solely to your own iPod selections – go back to the time before iPods and tune into the Top 40 of today.

Shazam

Ever ask yourself "What song is this?" when you miss the intro on the radio? Well Shazam should help you fix this problem. By holding your phone up to the source of the music and "tagging" the song, Shazam accurately tells you who sings the song, the title, the album artwork, and gives you links to share or even buy the song.
