The seemingly endless access to media, entertainment, and information that the internet provides is an indication that we live in an age of access. There is very little now that we can’t get by way of these categories. In the case of music and entertainment, there are several sites that stand out as providers of solid media information. In the case of music, sites for getting your tunes may include Amazon for purchasing mp3 from your favorite artists to sites like Grooveshark for getting your tunes in your mobile / internet ready library.
Grooveshark is somewhat similar to Pandora which is a site that uses the music genome project. This is a catalog of all kinds of songs. I don’t know what I’d estimate the number of songs at, but probably in the hundreds of thousands, maybe even in the millions. Whatever the number, this is a catalog or collection of the song name, title, artist, album, and more importantly for this topic, other characteristics that have to do with the song itself including the beat, the type of vocals, the genre, the musicality of the song, the melodic leanings, and several other components that are cataloged.
The sites that reference this project can then make suggestions based on what you like or the type of music you like by looking into their catalog for songs that match one more more of the components or characteristics that you’ve specified being a fan of in your interaction with the site. This is how Pandora works. This is far different from simply finding an artist on the radio and looking through mp3 indir directories and happening upon a few ftp servers and picking up a few extra mp3 files. This is far more intuitive and interactive.
In the case of getting the mp3 files so you can have them for later use, including making mp3 ringtones free of charge, you can usually get a link right from Pandora or one of the other sites that will take you through directly to Amazon or iTunes.
