We could probably list about 100 places in a list of places to upload your music to, but unless you have a dedicated promotional team working for you then you're not going to have much time available to keep 100 different sites updated with your latest news and latest tracks. So what 10 places are nearly essential in having a web presence for your music. From our experience we have gained the most listeners from this list of 10 sites and therefore we believe they are a must for uploading your tracks. They are in no particular order.

• MySpace - I doubt that anyone with an internet connection hasn't come across this site. It is almost essential to have a web presence here. Upload your tracks into the MySpace player, design your page and keep the MySpace blog updated with important news about your music.
• ReverbNation - While you cannot directly upload your music on Facebook, by using ReverbNation you can easily post your music to your Facebook account using their Facebook Apps. You will probably get some listeners through ReverbNation too and get to use lots of their cool features.
• TheSixtyOne - Upload your music and the name of the track stays hidden for 24 hours. Members of the site will spend their credits on liking your track, if lots of members like your track you're going to get on the front page. This site is a great way to get listeners and ultimately new fans.
• OurStage - Upload your music into their monthly contest and you will be paired up randomly with other tracks for people to vote on which one they like the best. More votes get you to the top of the leaderboard and ultimately to win prizes at the end of the month.
• Jamendo - This site lists tracks that have been released under a Creative Commons license, if you've made yourself an album there's no reason why you can't upload a few tracks to promote your other music. Maybe place some of your older tracks on there to draw in some new fans.
• SoundCloud - This site has some great looking widgets which allow you to paste your tracks elsewhere and we especially love the comment system where you can comment on a specific point in a track. Upload upto 10 tracks on a standard free account. If you want more you have to pay. But the amounts for a free account are pretty decent.
• Imeem - Create an artist account here and you can upload your tracks into their huge database of music. It is also a very social site allowing people to share music with each other.
• Last.fm - People who have the Last.fm application installed can share with friends what they've been listening to, but if you sign up for an account you can upload your music and it will appear on your artist page and be discovered when people search for similar musicians to ones that they already like.
• SoundClick - Upload your music to the SoundClick community and you'll be placed into the charts for each genre, you'll also get an artist page to link to your other social network accounts.
• iLike - Allows you to upload your music and more, apparently there is 50 million people using the service so it's a place you can't ignore. Also allows you to paste your music into Facebook like ReverbNation does above.

We know there are more sites out there to upload your music, but these 10 are our choice if you haven't got the time to upload to them all. So go get uploading your music and gaining new listeners and fans.
