Funderbird Cassette

The first full length album from the Michigan post-punk group FUNDERBIRD. Revisit hearing music like we did in the 80s and 90s. The true cassette tape listening experience. Fast forward, rewind, auto reverse .... all the hi-tech buttons ... Walkman not included because it got stolen at a party.

Verdict
The clearest difference is update cadence: iOSamp at every 2 weeks against Funderbird Cassette's every 5 months. Funderbird Cassette's advantage is iOS requirement (18.6 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
