Every upcoming and even established artistes out there wants a way to upload their songs for free, well who doesn't. Before I start to divert let me go straight to the point here are five (5) top sites to upload your music for free.
[b]Note: [/b]This list is in no particular order.

Soundcloud
Well this is probably the most popular of them all. With Soundcloud you get three hours of free upload. Meaning you can upload as many songs or podcasts as you can so as long as their total lengths do not surpass three hours. Once you exceed this limit you will be required to upgrade to a pro (6 hours) or pro unlimited (unlimited hours) account to have more hours. Soundcloud also integrates social features like re-posts, followings, likes e.t.c.

Mixcloud

Mixcloud is probably the best alternative to Soundcloud as this gives you unlimited uploads and streaming. The only possible downside to this site is the lack of a download feature. Tracks you upload can only be streamed and not downloaded. Mixcloud recently increased the max size per track to 100 MB.

MyNotjustok

This is a Nigerian option though not limited to only Nigeria. It can be used and accessed worldwide. MyNotjustok is a solution created by notjustok.com Nigeria's biggest music website as a way to allow artistes promote their music for free. Notjustok integrates some social featured like followings and re-posts. MyNotJustOk UI was recently revamped to feature an orange and black color scheme.

Reverbnation

Reverbnation is a music promotion tool used by millions of upcoming and established artistes worldwide.

LaspoVibes

This is a new entry into the Nigerian market created by the same team bringing you Tecep's Blog. It's still in it's inception and has stopped receiving entries as the developers strive to make a more automated solution like that of the others above.
