I recently passed 3000 plays on SoundCloud, which seems impressive to me considering I'm just messing about with music and upload whatever experiments I produce. Actually I've had a lot more plays, but they were on some tracks I did with my old band and you lose the plays for any tracks you later remove.
I accept that many of those 'plays' could just be some playing a few seconds and moving on. I suspect that having covers of some well known songs would cause me to appear in some searches. The wonder and frustration of music is that you can only find out what it is like by actually listening, in real time.
SoundCloud has been just what I wanted from a site to show off your music. I found it when I wanted to share the band tracks. Other sites had too many restrictions. I know MySpace does some of the same things, but I never joined that. The look of many of the pages there was enough to put me off.
I don't anticipate making money from music any time soon, so will probably stick with the free account, even though I could get more stats if I paid, and I like stats :)
I've also heard a lot of cool music there from friends and other bands I knew about or have discovered.
I plan to carry on playing, recording and sharing my music. Who knows, I may actually produce some good, original music one day, and I hope that my production skills will improve.
