How To Discern Between Indie and Emo Music

(This is an other article i found while researching on the net and in continuation of the ongoing Issue i have been writing about, i have uploaded here .I just wanna say sorry to the writer if i have infringed on her copyright Whatever)
Anyway here it goes:

Some independent bands may indeed have an Emo sound, but this does not make them the same thing. They are both blanket terms that cover not only musical genres but lifestyle choices as well.
A Snapshop of All Things Indie
Indie is a shortened term for "Independent Rock." Simply put, music that is produced independently instead of by mainstream corporations. Indie musicians are never confined by the restrictions of a major label, which gives them complete control over the quality and content of their music. While it may be more difficult to DIY in the music world, the rewards that accompany complete musical freedom are much more important to musicians taking this route.
There is no definite sound that accompanies the term Indie. Rather, there are no required musical rules and regulations to ensure that something is considered Indie. The only actual requirement is that a major label does not put out the music.
That being said, there is a certain sound that has developed within the Indie community. There are a great deal of emotive Indie bands that pride themselves on complex acoustic guitar lines and multi-faceted poetic lyrics. These bands, in turn, influence other bands and the signature sound is carried on. While these bands do tend to be more emotive than traditional bands, they aren't necessarily Emo. But it is obvious where the confusion comes from, as you may be able to list a few Indie bands under both terms (Elliot Smith, Bright Eyes, Cursive). Though, this sound, in no way represents all of Indie music as the term covers a wide range of artists and styles ranging from the angst filled punk rock of the band Saving Face all the way to the folksy antics of singer/songwriter Ani DiFranco.
A Snapshop of All Things Emo
The term Emo is relatively new, it refers to music that is particularly emotional or musicians that are partial to spontaneous and strongly emotional performances. While there are no clear qualifications to be considered an Emo musician,a certain sound is generally associated with the genre. Although, sometimes there is much controversy about whether or not to label a band Emo.
The Emo movement started out as a sub genre of hardcore Punk music, but that isn't necessarily true anymore. While many Emo musicians do embody the soft core Punk Rock spirit, this is not required. Emo music often employs soft guitar riffs accompanied by melancholy lyrics that tend to dwell on love and loss. This genre has been heavily marketed and has seen much commercial success in the recent past. There are no regulations on who can produce the music, it can be heavily corporate music or independently released as long as it is highly emotive.
Bands like, Alkaline Trio, Dashboard Confessional, Taking Back Sunday, AFI, Fall Out Boy and My Chemical Romance can all be considered Emo bands.
Thus, Indie and Emo music are quite different. Indie musicians must put out their own albums; this is what makes them Indie. Emo musicians must produce heavily emotional tracks, this is what makes them Emo. Again, they do cross over, but they are not the same thing.
