I spent some time yesterday evening looking for an equalizer that would work with my Soundcloud account. Finding this app and looking at it's features prompted me to download Soundy. After the installation, I signed in with anticipation to enriching my new (expensive) earbuds even more. After tapping on my selection, the play circle spun, and spun, and spun, then nothing. Checked my connection, I'm connected to the Internet.
I closed Soundy , loaded Soundcloud which played to my ears delight. Then I uninstalled this app, rebooted my iPad and reinstalled Soundy . No matter what I did, it never connected to a song to play anything.
I then went to the other iPad and tried with it. Same symptom.
So, packed with features? Yes! The only one I wish it had was to play Soundcloud. I have uninstalled it on both iPads.
