Pretty good but one pretty big problem

This is a really good streaming service but there is on big problem/glich with it. Songs that i have given the thumbs up to sometimes get the thumbs up taken away. Ive only noticed this in songs that are a different genre then I usually listen to, so that might have something to do with it.

Jamess bad review about iHeart: #1 for Radio, Podcasts, v8.1.1
