I bought it within the first hour of trying it. I personally HATE having more than one app to do a function, however this was a must have for me. I have some albums that are multiple artists and I much rather go by folder than the artist tags, so this works out well. Also, the EQ is truly a great tool. I thought it would be dumb at first but playing music in the car, I can tweak it to sound amazing.. And I love to listen to music in bed but my GF hates it, so the EQ lets me make it really quiet and just up the tones I need to hear.
He has a lot planned like a 'sleep timer' to fade out, even user saved EQ settings, and much much more. It is well worth the few bucks. If you complain about having to pay like 5 bucks for an app, try to code it yourself and give it away for a dollar. I bet you wouldn't! Feed the developers!!!!!!!!
