They could include at least one audio application so we can decide if it sounds good enough to buy. iPhone speakers are notoriously unpredictable. Bass always sounds crummy, but the highs are sometimes ok.

A transposition/clef changing feature will make this product even more awesome, especially for those who play transposing/bass clef instruments or who have music directors who change the key. Sure, we all have our own built-in transposer (aka the brain), but sometimes it's nice to just relax and play. I'll buy the full version if transposition is added.

I've been a long time subscriber of the Virtual Sheet Music site. I was really happy when they put their first app up. The previews were nice, but I was really hoping for full song versions with audio I could play along with. And here it is. Love being able to play different songs on the go. Hopefully, they'll add more than Christmas songs later.

I think it's great for violins and those who read the treble clef,like clarinet.I love the selections but wish they had audio with the song.I liked it otherwise :)).
