While it couldn't be easier to share images or links on Twitter, if you want to share actual files, music or documents, you have to make a little bit more of an effort to find services that make it easy to do so. If you already use a file sharing or backup service like Dropbox, it's very easy to generate a shareable link and post it on Twitter.
But if you'd rather keep things as secure as possible, there are several free services which make it easy to share all kinds of files on Twitter without having to sign up for a new service or having to grant access to your own computer.
Crunch.fm
Crunch.fm is the latest in free web apps that make it easy to share music on Twitter. After authorizing access to your Twitter account, search for the song or artist you want to listen to, and edit the text of your tweet.
The actual tweet is appended with the hashtag, #nowplaying.
Crunch.fm's search method is a bit odd. If you search for an artist, the site will come back with just one song, so you have to make your search very specific. The site also forces you to follow their Twitter account when you use it.
Swift.fm
After signing up for a free account, Swift.fm allows you to share mp3 files on Twitter by uploading them from your own computer.
After uploading the file from your computer, you can edit the text of the tweet and update your status.
While the text of the tweet is editable, you are forced to append the tweet with a mention of their Twitter account.
When users click on the link, the song will automatically begin playing.
TinySong
TinySong harnesses the power of Grooveshark, allowing users to easily share music on Twitter, without having to sign up for an account. After searching for the song you want to share, you should be able to preview it directly on TinySong but the feature is hit and miss.
Hitting the share button will generate a shortened URL which you can copy to your clipboard.
Hitting the Twitter button automatically populates your tweet for you.
The TinySong link will take users to Grooveshark.
TwitDoc
If you want to share documents with other Twitter users, TwitDoc allows you to upload files to your TwitDoc account, and when uploading, you can chose whether or not to tweet the link straight away.
If you do choose to tweet through TwitDoc, they do not append anything to your tweet.
The document can be then be accessed through Scribd.
Twi.tt
With Twi.tt you can share almost any kind of file through Twitter, whether an audio or video file, a document, or even a poll.
After you've authorized the website, select the kind of file you want to share, enter the text to your tweet and send it to your followers. Photos can be uploaded from your computer, shared from a URL or captured using your webcam.
Videos can be uploaded, shared using a URL, or recorded using your webcam.
Documents can be uploaded or shared using a URL.
And lastly, polls can be created using the form on the site.
The poll then be available from a link posted on your Twitter account.
Sharing audio files is a feature that is yet to be activated on Twi.tt.
