MP3

MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a digital audio encoding format using a form of lossy data compression.
It is a common audio format for consumer audio storage, as well as a de facto standard encoding for the transfer and playback of music on digital audio players.
MP3's use of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners, but is not considered High Fidelity audio by the elite connoisseur. An MP3 file that is created using the mid-range bitrate setting of 128 kbit/s will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bitrates, with higher or lower resulting quality.Reference : http://en.wikipedia.org/wiki/Mp3

MP4 versus

The existence of two different file extensions for naming audio-only MP4 files has been a source of confusion among users and multimedia playback software. Since MPEG-4 Part 14 is a container format, MPEG-4 files may contain any number of audio, video, and even subtitle streams, making it impossible to determine the type of streams in an MPEG-4 file based on its filename extension alone. In response, Apple Inc. started using and popularizing the .m4a file extension. Software capable of audio/video playback should recognize files with either .m4a or .mp4 file extensions, as would be expected, as there are no file format differences between the two. Most software capable of creating MPEG-4 audio will allow the user to choose the filename extension of the created MPEG-4 files.

History of MP4

MPEG-4 Part 14 was based on Apple’s QuickTime container format. MPEG-4 Part 14 is essentially identical to the QuickTime MOV format, but formally specifies support for Initial Object Descriptors (IOD) and other MPEG features.

Aggregators

Aggregators such as The Hype Machine and Elbo.ws track MP3 blog posts and display the most recently updated posts on its front page. The services are meant to provide a snapshot of what's going on in music blogging and make it easier to search through recently posted MP3s. The Hype Machine features a list of the most popular tracks of the last 3 days as well as the most blogged bands and most popular searches. Elbo.ws has a similar feature listing which Bands, Tracks, and Videos are currently "hot." Music Blog Aggregators have caused a boom in MP3 blog readership and accessibility. Aggregators use RSS technology to collect data from MP3 blogs and link to the individual blog posts instead of directly to the MP3s.

MP3 blog History 2

In 2006, Rolling Stone did an article tracking "blog buzz" called First Hype, Then Kill with the subtitle "How the geeks who control the music blogosphere destroy the bands they love." [2] It followed the hype of bands like Tapes N' Tapes, Clap Your Hands Say Yeah, Arctic Monkeys and Cold War Kids. While the article brought exposure to mp3 blogs, it was blasted on blogs for misrepresenting what impact they have on a band's career. According to the chart, Gorilla vs Bear giving a good review of Cold War Kids was the highpoint of the band's career, and signing a record deal marked the beginning of their decline. It also assumed that music blogs have collective opinions instead of an array of many different musical leanings.[citation needed]
In 2006, Sirius Satellite Radio began broadcasting "blog radio", a show on the College/Indie Rock channel Left of Center. The show lets music bloggers talk about the latest in the indie-rock scene.

MP3 blog History

Among the very first MP3 blogs were Fluxblog and Stereogum. The latter began as a music-related LiveJournal in 2002, though its format was focused on indie/pop gossip rather than MP3s. Fluxblog's trumpeting of LCD Soundsystem's "Yeah (Stupid Version)" in early 2004 brought increased attention to MP3 blogs. A May 2004 story on National Public Radio[1] further galvanized the trend, and today there are thousands of MP3 blogs covering a cornucopia of musical styles.
A significant number of indie music labels, promotional agencies and hundreds of artists regularly send promo CDs to MP3 blogs in the hopes of gaining free publicity. Major labels with small acts to promote have also attempted to use MP3 blogs. In 2004, Warner Bros. gave permission for a song by their act The Secret Machines to be posted by the MP3 blog Music (For Robots). This drew attention not only for the song and the label granting permissions, but also due to the fact that several comments praising the track came from IP addresses within the Warner Bros. network. The publicity generated by MP3 blogs crossed the line from the internet to TV in early 2005, when Music (For Robots) was featured during MTV's Total Request Live program for bringing the Hysterics, a Brooklyn rock band composed of four 14 and 15 year-old high school students, to the network's attention.
