I used Amuse too, but can't say I got too much from it. You have to decide on your goals and I'm happy enough if a few people hear my music. I can put it on Youtube too for free. Not really looked much beyond that.
I do think that Bandcamp is a good option as you can put stuff on for free and people can pay for it. They have days where there are no fees on sales.
Band camp, that's it, I was trying to remember the bloody site name, I'll get that sorted too. Only have the 'bring me love' song fully produced, and will put out albums at a time, rather than singular songs.
I think Bandcamp can work better with albums, but some people put out singles too. You have to work on building up your fans.
