Songs Not Counting

I've noticed lately that a lot of the songs I listen to aren't being logged, so I tested it today. I listened to 17 songs on my 45 minute drive home. Only 4 songs counted in my stats.fm, and I'm pretty sure it's only the ones I listened to entirely to the very end and very last second. I skipped a song 35 seconds in, 1 minute in, 2 minutes in, and even 15 seconds before the end of the song, and none of them show on my streams for today.
