Good app, but needs more work – iMashup Review

The app "iMashup" has worked wonders for me in the past. That being that I can make awesome mashups and such, but the only complaint I currently can say is that there still (and for maybe like two years) hasn't been an update addressing the delete button in which you can delete your mashups if you didn't want them anymore or simply if they didn't go right. Another bug I came upon is that a song I put into the app has been all weird, by this I mean the song I put in started slow but sped up a lot at the end. Not sure why the app did that, but please fix some of these minor problems developers of the app (Mixed in Key) please.
