There is an option to save an album, then find it in your saved albums, click the options (...) at the top right hand corner of the screen and tap 'Like all songs'.
Admittedly, this requires more work vs the desktop application as there's no option to select all songs by the artist at once and saving them to 'Liked Songs', but an easy workaround is save most of the songs/albums via desktop or laptop before you venture out with your mobile device, which is a lot easier.
I still don't know why Spotify made this decision though, it was better before this update (psssh).
Re: New Liked Songs and Saved Albums problem [FIX]
This does work on a desktop. Thanks for the work around!
However, the reality of how I mostly utilize the service is through my cell phone during my commute to and from work. And while I'm glad to be able to add stuff more easily on my macbook, I'd prefer it to be easier on the app. I listen to a little more than 10 hours a week through the app.
I'm not actually sure how I should use Spotify anymore. If I save an album, I consider all songs from that album to be in "my library" and so if I shuffle all songs in my library I want the songs in that album to be included. I guess I should just "like" all songs in an album as well, but isn't that going to mess with Spotify's recommendation engine? Because I don't actually "like" all those songs, I just want them in my library. Specific songs I particularly like is different.
Ugh... I have no idea. I guess this is why I pay for Apple Music as well!
This is a radical change in the user experience. The problem is that there is no way to easily access *every* song in my collection, either liked individually or contained in a liked album. Before I could put all of my collection in shuffle play with two clicks. Now, to have the same result, I have to like both an album and every single song in it. This is a poor user experience.
I've expressed my frustration to this issue as well on Twitter. Now I have replicating songs appearing in my albums and Liked Songs list as well. Ex. If I have an album saved from BEFORE this change went into effect, I have those individual songs appearing in the Liked Song list as well. It's a mess. Complete un-navigatable mess.
I liked saving specific songs from certain albums, now those albums aren't there and the songs are in my list of Liked Songs which is beyong bloated with duplications.
