Used that maybe 50+ times, it NEVER gave me anything remotely accurate.
Same here. I'm sure it would work if I already knew the song I'm humming, and could sing the lyrics, but that would defeat the purpose of the service.
I have great melody memory, terrible title and lyrics memory, and good pitch, and it has never helped me the many times I've tried to figure out what song I got in my head.
Midomi is fantastic. We made a game out of it: you'd pick a song a try to sing it to Midomi (not hum). If it guesses what you are singing, you score. Note this is for amateurs and for drinking parties :) it doesnt have a lot in the catalogue, but it has enough. Super fun :)
Came here to look for this. IIRC Midomi launched as an app for feature phones? (Razr-era)
