Well, it seems that there’s at least one common pattern here - that AotC, bar two very good tracks, is the most disliked soundtrack of them all. Probably the movie, too. But I digress.
I think that the TFA soundtrack has a lot of great themes, such as Rey’s Theme, March of the Resistance, Sherzo for X-Wing’s, and The Jedi Steps, but I think that most of the other tracks are like filler (Rey Meets BB-8, That Girl with the Staff, Finn’s Confession, Maz’s Counsel, Snoke). They are all good, but nothing especially memorable. I also think that the great themes (stated above) aren’t as good as the themes from AOTC, or any other films really. Across the Stars, The Chase Through Coruscant, Jango’s Escape, Bounty Hunter’s Pursuit, Return to Tatooine, Love Pledge/The Arena and Confrontation with Count Dooku and Finale are all exceptional tracks that I find myself humming very often. The only reason I rank the AOTC soundtrack so low is that there really wasn’t that much music composed, although what was is brilliant, and in my opinion, better than TFA.
