Lenovo is currently listing a 4 month trial for new users of Amazon Music Unlimited. The regular trial is usually 1 months. There's currently a 3 months trial if you sign up directly at https://www.amazon.com.au/music/unlimited no later than 28 April. There's no listed expiry date for the lenovo 4 months trial.
To get this deal, lenovo requires a credit card which will be charged at the regular $11.99 per month if amazon music is not cancelled at the end of the trial. Cancellation is done with the lenovo store used to "purchase" the trial.
After Tidal screwed up with MQA, I need Amazon as that's the only streaming service that shows up as 24bit on my AVR. I am seriously considering prime now to keep this service going.
